ChiaPing Tsai commented on HBASE-15806:

The bug posted on the [HBASE-16071|https://issues.apache.org/jira/browse/HBASE-16071] will
introduce an incorrect result when we test the "delete" and "raw scan" on the security hbase.

I will give a patch of the [HBASE-16071|https://issues.apache.org/jira/browse/HBASE-16071]
 before this issue's

> The time for exporting table can be reduced, if we use the endpoint technique to export
the hdfs files by the region server rather than by hbase client.
> In my experiments, the elapsed time of endpoint-based export can be less than half of
current export tool (enable the hdfs compression)
> But the shortcomings is we need to alter table for deploying the endpoint
> any comments about this? thanks
