Subject [jira] [Commented] (HBASE-15548) SyncTable: sourceHashDir is supposed to be optional but won't work without
Date Mon, 28 Mar 2016 18:41:25 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15548?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15214653#comment-15214653
] 

Dave Latham commented on HBASE-15548:
-------------------------------------

Sorry for the discrepency between the usage information and the actual behavior.  As you discovered,
the sourcehashdir is required at the moment.  You may have found it already, but to generate
the hash data, you can run `org.apache.hadoop.hbase.mapreduce.HashTable`

> 1) SyncTable code is contradictory. Usage said sourcehashdir is optional (https://github.com/apache/hbase/blob/ad3feaa44800f10d102255a240c38ccf23a82d49/hbase-server/src/main/java/org/apache/hadoop/hbase/mapreduce/SyncTable.java#L687).
However, the command won't run if sourcehashdir is missing (https://github.com/apache/hbase/blob/ad3feaa44800f10d102255a240c38ccf23a82d49/hbase-server/src/main/java/org/apache/hadoop/hbase/mapreduce/SyncTable.java#L83-L85)

> 2) There is no documentation on how to create the desired sourcehash
