> enable_table_replication can not perform cyclic replication of a table

> Key: HBASE-17460

> Reporter: NITIN VERMA

>
> The enable_table_replication operation is broken for cyclic replication of
> HBase table as we compare all the properties of column families (including
> REPLICATION_SCOPE).
> Below is exactly what happens:
> 1. Running "enable_table_replication 'table1' " opeartion on first cluster
> will set the REPLICATION_SCOPE of all column families to peer id '1'. This
> will also create a table on second cluster where REPLICATION_SCOPE is still
> set to peer id '0'.
> 2. Now when we run "enable_table_replication 'table1'" on second cluster, we
> compare all the properties of table (including REPLICATION_SCOPE_, which
> obviously is different now.
> I am proposing a fix for this issue where we should avoid comparing
> REPLICATION_SCOPE inside HColumnDescriotor::compareTo() method, especially
> when replication is not already enabled on the desired table.
> I have made that change and it is working. I will submit the patch soon.
