--------------------------------------------------
[~samarthjain] FYI as part of PHOENIX-3496 exactly solving the same problem.
Just retrying opening scanner until the column family added. May be same thing
helps in case of modifying column family cases as well.
> Reduce chances of tests flapping with ColumnFamilyNotFoundException for HBase
> 1.x

> 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.
