Space quota change after quota violation doesn't seem to take in effect

Steps followed 

• Through hbase shell

  set_quota TYPE => SPACE, TABLE => 'TestTable', LIMIT => '2M', POLICY => NO_INSERTS

• Run PE until the quota is reached

  hbase org.apache.hadoop.hbase.PerformanceEvaluation --nomapred --rows=20000000 sequentialWrite 1

• Through HBase shell

  set_quota TYPE => SPACE, TABLE => 'TestTable', LIMIT => NONE

  - Through HBase shell verify the effective Quotas

  > list_quotas

• Wait for some time (at least 5 mins) and try to add data to the table

  > put 'TestTable','r1','info0:0','v1'
  ERROR: org.apache.hadoop.hbase.quotas.SpaceLimitingException: NO_INSERTS Puts are disallowed due to a space quota.

  To resolve the issue, RSes need to be restarted which points to in memory data not getting reset.
