> 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).
