Re: Hbase to hive

[samir das mohapatra]

Hbase with hive provides the result handler , which will take the  java
classes , so you can write your own code for you BL.

Re: Hadoop - Distributed sorting

[samir das mohapatra]

Hi
  Steps to do this:
1) Map: It will only define the key value for each number
 2) Combiner : To sort locally  over chunk of dataset .
 3) Reducer: It will sort after over whole chunk globally-->
OUT PUT as sorted

Note: set combiner and reducer as Same class.

Example:
  Let us assume that our data set (integers) is constrained between 100 to
200 and we have 5 files each containing 1000 random integers between 100
and 200 (so a total of 5000 integers between 100 and 200). We read each
file into a Map and then in the Reduce phase, we produce a final Map which
contains the count of all the integers. Now if we sort all the integers
from the final Map and output it
into a list data structure in the form of  then we have
sorted all the data (see figure below). Aside : In Java, you don’t even
have to come up with the data-structure that I am talking about, if you
just use a 
TreeMapin
the final Reduce phase, then all the keys (i.e. data) are already
sorted
as long as the key type (e.g. String, Integer, etc.) implements the
Comparableinterface
(
Hadoop  has something similar called
WritableComparableand
I am using a TreeMap that takes Strings as keys in
Reducer


Thanks
