> The normal flow for region merge is:
> 1. client sends a master RPC for dispatch merge regions
> 2. master moves the regions to the same regionserver
> 3. master calls mergeRegions RPC on the regionserver.
> For user initiated region merge, MasterRpcServices#dispatchMergingRegions()
> is called by HBaseAdmin.
> There is no coprocessor invocation in step 1.
> Step 3 is carried out in the "hbase" user context.
> This leaves potential security hole - any user without proper authorization
> can merge regions of any table.
> Thanks to Enis who spotted this flaw first.
