How can we run in more than 1 iterations using snapshot pls

dheeraj_madaan · ‎09-20-2016

I am sorry Nitin, don't have much understanding for HTableAPI, if you could suggest some different command please. or is it possible to copy few data(say few columns ir rows) using snapshot so that I can copy in 4-5 iterations.

Thanks Nitin, But I had already tried snapshot and clone and it's taking huuge time

I wanted to copy data from one HBase table to another, but it's taking Huuuuge time to do the same and meanwhile other jobs in cluster are failing due to same. I tried below 3 techniques and still time taken is on a higher side. Can you suggest some efficient approach for the same. 1) org.apache.hadoop.hbase.mapreduce.CopyTable 2)org.apache.hadoop.hbase.mapreduce.export 3)take snapshot of the table, then clone the snapshot into another table Thanks in advance..

Hi, I understand to compress existing HBase table we can use below technique.. disable 'SNAPPY_TABLE' alter 'SNAPPY_TABLE',{NAME=>'cf1',COMPRESSION=>'snappy'} enable 'SNAPPY_TABLE' However did you find a way how to compress existing data, as only new data is getting compressed. Your help is much appreciated. TIA, Dheeraj Madan
