Lou DeGenaro commented on UIMA-6033:
------------------------------------

Fix is as follows: if the invocation of start_ducc results in database start, 
then run new DbUpdate class which in turn calls 
RmStatePersistence.getAlterList() to get schema alter statement(s) which are 
then applied to the running Cassandra.  The alter statement(s) comprise the new 
column "quiesced".

Note that altering schema to add a column that already exists is harmless.

> quesced column not created when extending from older DUCC DB restore.
