shardul-cr7 opened a new pull request #572: HBASE-22012 SpaceQuota DisableTableViolationPolicy will cause cycles of enable/disable table
URL: https://github.com/apache/hbase/pull/572
 
 
   Space Quota: Policy state is getting changed from disable to Observance after sometime automatically.
   
   Steps:
   
   1: Create a table with space quota policy as Disable
   2: Put some data so that table state is in space quota violation
   3: So observe that table state is in violation
   4: Now wait for some time
   5: Observe that after some time table state is changing to to Observance however table is still disabled
   
   Solution:  it is better to not remove the entries from cache regionSizes if table is in violation and has DISABLE policy set on it to avoid this repeat cycle of enable/disable. If the entries are not removed from the cache for disable policy and violation tables the table will not go from disable to enable even though regions of the table are offline.
