Hive - Part 2

.

Hive was developed by facebook .

• It is a data warehouse system built on Hadoop.
• Helps you to define a structure for you massive unstructured data
• Simplify analysis by using SQL like scripting language.(Hive QL)

Hive is NOT : 

1. A Relational Database
2. Designed for OLTP.
3. Suited for real time updates  

Use Cases:

Ad hoc queries

Analysis

Summarization  

Hive components:

Hive Clients (Thrift,JDBC,ODBC)

Hive Services (CLI(Command Line Interface), HWI(Hive web Interface))

Hive Metastore

The metastore is the central repository of Hive metadata. The metastore is divided into two pieces: a service and the backing store for the data. By default, the metastore service runs in the same JVM as the Hive service and contains an embedded Derby database instance backed by the local disk. This is called the embedded metastore configuration.

In Hive Insert statement is used to populate data.

We can load data to the table from local disk or HDFS.

Teaching Children

I have always been inspired by children. Every time i see a child, i see a ray of hope. If my present sucks, i can work harder to make sure kids get better future. Well in fact this is what every parent wants. Some thing is very wrong in our system. Children are being robbed of their innocence and are stressed out. I have recently started taking youth courses for Juvenile Kids. They are no different then other kids.
Today was my first day.
While packing up one of the kids i had never spoken to helped me pack my yoga mat. I was touched by his gesture. They asked me if i would come back again to teach them yoga the next day. :) :)
On weekdays i go for an hour to teach theses kids yoga.
If you would like to contribute in any capacity please let me know.

Hive Essentials (Part 1)

This Post will be dedicated to Hive:

What is Hive?.
Hive is a data warehouse that sits on top of Hadoop .

Online Resources
http://en.wikipedia.org/wiki/Apache_Hive

Hive Queries run as Mapreduce Jobs under the hood.

Hive Components:
Hive MetaStore
a) Table Definition, Indexes and partitions
b) Stored on the Local Machine on Derby Database
Hive Qurey Engine

Basic Sytnax:
Show Tables;//Shows All tables
Describe
; //Describes the schema of the table

CREATE TABLE sample(firstName STRING, lastName STRING, id INT)
ROW FORMAT
DELIMITED FIELDS
TERMINATED BY ‘ ‘
LINES TERMINATED BY ‘\n’
STORED AS TEXTFILE

Hive - Which stung me during (Hortonworks) my exam

Whohoo i failed the Hortonworks practice exam as i had mostly concentrated on Mapreduce , Hbase and Pig. I have a big over confidence Problem. :)
This exam is totally free you can give it 2 times.

I would say your test would mostly be :

30% Mapreduce
30% Pig
30% Hive
10% Hbase + Hcatlog

Prepare well and best of luck dont make the mistakes i made :).

Gadgets that make me go GAGA

Well today i have decided to write about the gadgets that i use on a daily basis. Me and my gadgets have a very complicated relationship, it began when i was 9. A brand new 486 PC with windows 3.1. Wait .... hold on this started way before i was 9.

My first toy was a Brick. At a tender age of 5, I was the master of Tetris. We used to have challenge rounds where i used to compete with Dad and Sis. Half a dozen bricks later ( some of the died,some submerged in water and most of them were subjected to military grade drop tests). 

Later i graduated to Terminator. Well those poor souls who don't know what Terminator is ... it is a 8 BIT video game. Wow 8BIT!!!. It worked on Cartridges. My favorite game was not Tetris, It was Contra which is as good as it gets (Esp. when you worked with a buddy on Multiplayer mode). My sister hated the game.
I used to plug in my console when my parents were asleep ( Happy Hours :) )
I would like to recall one incident very clearly, One day when i did not share my TV Video game with my Sis. Guess what she did?. To my horror ,She picked up my console and threw it out.(Yes i have had a very troubled childhood). I cried for days but i got over it. ( It was tough) . Again after 3 8bit Consoles / TV video Games i moved on to Nintendo.
(1 destroyed by sis, 1 joysticks stopped working, 1 again destroyed, don't remember by whom by i suspect my Sister).

More on Part 2 of the post!.

Sri Sri Yoga

I have been wanting to write about Yoga for a long time. Yoga for me now is not just Asanas, its a lot more than that. Doing Asanas was a pain (literally). Touch here touch there .... weird poses. I literally used to skip the warm ups so that i can do my meditation. But alas life is not so simple. My body started rebelling and knees started hurting (I promise you that meditation is not possible even if your with god himself). This was when i woke up to the fact that meditation and yoga are complementary. During one of  the Yoga sessions i found that i was in completely meditative state yet in action. This was a very very new experience for me. Doing Yoga is definitely not about stretching more than other person.

I had sinus since i was in 4th std+back ache. Today i am a free birdie.

If you are deeply in love with yourself ,do come and attend Sri Sri Yoga.
(We will be preparing for Yogathon an all india national event where we will nail 108 suryanamaskars..... and yes certificates will given ....... ) .

Minor Side effects :
a) Increased Intuition
b) Happiness
c) Weight loss / Weight gain
d) Bye bye back ache!.

THAT FIZZY FEELING

I am republishing this post !! .....

This post is dedicated to my sister for making my life so much easier. I was studying in Hyderabad and I had a group of friends in my colony with whom I would hang out. One of them was like 5 years older than us. His name was Raj. Every one used to use the choicest of words to curse him b'cos of the simple fact he was too old (he looked like a nerd too). Well one day he came up to me and said "Krishna do you want to have something to eat" I obviously said yes and 15 minutes later I was happily munchin chips and had a bottle of Mountain dew to drink.This routine continued for a month and steadily my friends got jealous because he was'nt treating them. One day Raj came up to me and told me that he was in love with my sister and he wanted my help to woo her.
Well I considered my options :

1) He was too ugly. My sister would never fall for him even if all the angels and the gods were with him.

2) C'mon Gross!..... which loser would tell someone's brother that he loves his sister! it is the most pissing off thing one can do.

3) AND the most important thing >>Chips(Lays) and Aerated Drink(Mountain dew)<< every day for the rest of my life.

Well my friends knew about this and did all the things possible to stop me from accepting coke and chips. "C'mon man, its your sister!, If someone said something like that to my sister my brother would beat the crap out of him" said Sarfu. Sarfu had a brother whose name was Rizwan and his occupation was in import/export business. He had lot of friends and they used to go around in bikes. Well i didn't have a brother, I figured that god has given me brains, using my yukti I didn't say anything. This treating went on for few months but Raj wanted results I didn't help him a bit.

One day he got tired of treating me and said he is going to say the three letter word to my sister. My response : "No. leave my sister alone!".

He got angry and said "Its gone too far already". Well, he had never spoken to my sister or even remotely tried. I think he was referring to the money he had spent on treating me with Chips and Coke every day.

In full josh He decided to go to my house and tell my sister the dreaded three letter word. I was damn scared for myself if Raj spilt the beans that he was treating me every day. Mom and Dad would definitely not be pleased. Well he went home met Dad and after that the details are vague because i wasn't there, it seems my Dad told him to concentrate on studies and forget about it. That was the last day I got my treat. Later on when i spilled the beans to my sister she got pissed because I didn't share the coke and the chips with her.


Moral of the story: coke and chips are unhealthy.

Balchetna Shibir

 Well i cannot imagine getting up @ 6 in the morning without a reason. Past few days the reason for waking early and doing my practice early are these cute little innocent kids!!. I guess i am learning more from them :D. Teaching 150 kids!!!this is as good as it gets. (There is always one kid talking, One kid throwing stones at others and one kid fighting at any given point to time). My life feels more useful at the end of the day. Today was the third day of the workshop. We shared a very stupid joke and all of them burst out laughing. Comon i am known for my horrible pjs but when you have audience which really appreciates ..... nothing like it  :D.
I am taking this beautiful course with Kiran. Kids love him. They love him so much that while playing the game they think he is a participant and form groups with him. Kiran being Kiran gives instruction for the course and also for the group he is in. At this juncture i do not know who is teaching whom. 1 word to describe this course is UTTER CHAOS and CELEBRATION!!. I can feel that god through them. This post is dedicated to '150 Beautiful KIDS who literally rock my world'.
