[jira] [Created] (HBASE-8844) Document stop_replication danger

Patrick created HBASE-8844:
------------------------------

             Summary: Document stop_replication danger
                 Key: HBASE-8844
                 URL: https://issues.apache.org/jira/browse/HBASE-8844
             Project: HBase
          Issue Type: Task
          Components: documentation
            Reporter: Patrick
            Priority: Minor


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).
