stack commented on HBASE-3904:
------------------------------

So, how do you think this should work Vidhya?  isTableAvailable won't ever know how many regions there are supposed to be in a table.  Checking for > 0 is probably the best it could ever do.  It sounds to me like we need something else or that after isTableAvailable returns true, that then you should get an HTable instance and call http://hbase.apache.org/apidocs/org/apache/hadoop/hbase/client/HTable.html#getRegionsInfo() in a loop with a bit of wait until the number of regions comes up to close the number you passed to create table?  (FYI: I haven't tried this to see if it will work).

> This function as per the java doc is supposed to return true iff "all the regions in the table are available". But if the table is still being created this function may return inconsistent results (For example, when a table with a large number of split keys is created).
