Hi All, I have query regarding hbase data migration from one cluster to another cluster in same N/W, but with a different version of hbase one is 0.94.27 (source cluster hbase) and another is destination cluster hbase version is 1.2.1.
I have used below command to take backup of hbase table on source cluster is: ./hbase org.apache.hadoop.hbase.mapreduce.Export SPDBRebuild /data/backupData/ below files were genrated by using above command:- drwxr-xr-x 3 root root 4096 Dec 9 2016 _logs -rw-r--r-- 1 root root 788227695 Dec 16 2016 part-m-00000 -rw-r--r-- 1 root root 1098757026 Dec 16 2016 part-m-00001 -rw-r--r-- 1 root root 906973626 Dec 16 2016 part-m-00002 -rw-r--r-- 1 root root 1981769314 Dec 16 2016 part-m-00003 -rw-r--r-- 1 root root 2099785782 Dec 16 2016 part-m-00004 -rw-r--r-- 1 root root 4118835540 Dec 16 2016 part-m-00005 -rw-r--r-- 1 root root 14217981341 Dec 16 2016 part-m-00006 -rw-r--r-- 1 root root 0 Dec 16 2016 _SUCCESS in order to restore these files I am assuming I have to move these files in destination cluster and have to run below command hbase org.apache.hadoop.hbase.mapreduce.Import <tablename> /data/backupData/ Please suggest if I am on correct direction, second if anyone have another option. I have tryed this with test data but above command took very long time and at end it gets fails 17/10/23 11:54:21 INFO mapred.JobClient: map 0% reduce 0% 17/10/23 12:04:24 INFO mapred.JobClient: Task Id : attempt_201710131340_0355_m_000002_0, Status : FAILED Task attempt_201710131340_0355_m_000002_0 failed to report status for 600 seconds. Killing! Thanks Manjeet Singh
