Hive Tutorial 2 : Why to use hive

Hadoop is the future of enterprise data management.
Apache Hive is the gateway for business intelligence and visualisation tools integrated with Apache Hadoop.
Learning Apache Hive puts developers on the path to innovate on new data architecture projects and new business applications. I think it’s always more exciting to write code for something that’s ramping up, rather than for maintaining mature systems.

Learning Hive is easy for those who already know SQL.

Facebook originally created Hive because they had a pressing need to analyse their petabytes of data at Internet scale. But they did not have enough time to teach all of their data analysts to write Java programs that would kick off Map Reduce jobs.

Their analysts already knew how to write SQL queries, so Facebook created Hive as a tool those analysts could use with their existing SQL skills. After Facebook contributed their code to the Apache Foundation, the open community continued developing Hive along these same lines. So the same is true today as it was in the beginning: developers already familiar with SQL and then take part in all of the new opportunities promised by Hadoop v2.0.

Hive Tutorial 31 : Analytic Functions

Image
Hadoop Hive analytic functions compute an aggregate value that is based on a group of rows. A Hadoop Hive HQL analytic function works on the group of rows and ignores the NULL in the data if you specify Hadoop Hive COUNT Analytic Function Returns number of rows in query or group of rows. Syntax: COUNT(column reference | value expression | *) over(window_spec) For Example; select pat_id, dept_id, count(*) over (partition by dept_id order by dept_id asc) as pat_cnt from patient; at_id dept_id pat_cnt 6 111 4 2 111 4 5 111 4 1 111 4 4 222 3 5 222 3 3 222 3 7 333 1 8 444 1 Hadoop Hive SUM Analytic Function Just like count function, sum Hive analytic function is used to compute the sum of columns or expression. Sum analytic function is used to compute the sum of all rows of table or rows within the groups. Syntax: SUM(column | expression) OVER( window_spec) For example: Calculate sum insured amount of all patients within each department...

Hive Tutorial 37 : Performance Tuning

Performance plays key role in big data related projects as they deals which huge amount of data. So when you are using Hive if you keep few things in mind then we can see dramatic change in the performance.  Performance tuning in hive: Partitions Bucketing File formats Compression Sampling Tez Vectorization Parallel execution CBO Partitions : The concept of partitioning in Hive is very similar to what we have in RDBMS. A table can be partitioned by one or more keys. This will determine how the data will be stored in the table. For example, if a table has two columns, id, name and age; and is partitioned by age, all the rows having same age will be stored together. So when we try to query based on age range, then hive will retrieve the data by going into particular folders instead of parsing through whole data. /hdfs/user/tablename/age/10 /hdfs/user/tablename/age/11 Bucketing : Bucketing is more efficient for sampling,data will be segre...
