Subject [jira] [Commented] (HBASE-13022) "RegionException: Retries exhausted..." ERROR in HBaseAdmin.disableTable(...) if hbase.client.pause=0

    [ https://issues.apache.org/jira/browse/HBASE-13022?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14318931#comment-14318931

Andrey Stepachev commented on HBASE-13022:
------------------------------------------

That would introduce discrepancy in what this property is for. Here should be either different
property or just warning.
I'd not change this behaviour as you propose because currently it behaves as expected: zero
pause is exactly zero.

> If hbase.client.pause set to 0 it breaks retry back-off logic in HbaseAdmin.getPauseTime()
for DDL operations. Operation succeeds because it happens asynchronously but caller get an
Exception because caller thread did not wait for operation to complete:
