[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).
