Nihal Jain commented on HBASE-17942:
------------------------------------
bq. Add table name to the log and exception message in split/merge procedure?
This is what is logged, I don't think we need to print table name explicitly.
WDYT?

> Snapshot of a large tables usually fails when region split/merge happens
> during snapshot. HBASE-15128 has introduced enable/disable switch for split
> /merges, but only cluster - wide which is not always good in a large
> deployments. The new feature will improve snapshot stability ands performance
> for a single table.
