Zhihong Yu commented on HBASE-4991:
-----------------------------------

For:
{code}
+  public int getRegionsCount(byte[] regionName) throws IOException;
{code}
regionName is used to extract table name. We should rename the method to, e.g. 
getRegionsCountForTable().

w.r.t. utilizing code from Merge, I looked at Merge.mergeTwoRegions() and saw 
no fault handling code.
I think if we add fault-tolerant code to Merge, it might look similar to what 
Mubarak has now.
