>                 Key: HBASE-20861
>                 URL: https://issues.apache.org/jira/browse/HBASE-20861
>             Project: HBase
>          Issue Type: Bug
>          Components: Replication
>            Reporter: Pankaj Kumar
>            Assignee: Pankaj Kumar
>            Priority: Major

> Steps to reproduce:
> 1. Add a peer
> 2. Enable a table replication
> 3. Put data
> 4. remove peer
> 5. Truncate the table in both the cluster
> 6. Add peer
> Observation:
> Here the old data is getting replicated in the table in peer cluster.
> HBase replication by design upon peer addition always starts replication from begining
of WAL file, so all replicable wal entries get replicated irrespective of peer addition time.
> This can be handled by skipping WAL entries which is having create time before peer addition
time.
