Subject [jira] [Commented] (HBASE-8844) Document stop_replication danger
Date Mon, 09 Jun 2014 15:59:02 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8844?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14025308#comment-14025308

Jean-Daniel Cryans commented on HBASE-8844:

[~misty] I was about to commit and was double checking the documentation and I figured that
we should remove the whole "state znode" section since that was also connected to start/stop_replication.
I can do it on commit if that's ok with you.

> The first two tutorials for enabling replication that google gives me [1], [2] take very
different tones with regard to stop_replication. The HBase docs [1] make it sound fine to
start and stop replication as desired. The Cloudera docs [2] say it may cause data loss.
> Which is true? If data loss is possible, are we talking about data loss in the primary
cluster, or data loss in the standby cluster (presumably would require reinitializing the
sync with a new CopyTable).
