Samarth Jain updated PHOENIX-4176:
----------------------------------
Description: In HBase 1.x, when adding a new column family, the check to
detect whether the HTableDescriptor is updated isn't enough. Tests that add a
new column family run the risk of flapping when number of regions on the table
are high (since the column family has to be added to all the regions). Till we
figure out a permanent solution for this, we can possibly decrease chances of
such tests from flapping by reducing number of regions/pre-splits and possibly
configuring hbase.online.schema.update.enable to false in our tests. (was: In
