Sakthi commented on HBASE-20705: -------------------------------- FYI: Even after the patch, this problem can be reproduced if the "hbase.quota.remove.on.table.delete" is set as false. HBASE-21225 has been opened to solve the issue where space quota removal(using 'NONE') doesn't happen completely if a rpc quota is already set. > Having RPC Quota on a table prevents Space quota to be recreated/removed > ------------------------------------------------------------------------ > > Key: HBASE-20705 > URL: https://issues.apache.org/jira/browse/HBASE-20705 > Project: HBase > Issue Type: Bug > Reporter: Biju Nair > Assignee: Sakthi > Priority: Major > Fix For: 3.0.0, 2.2.0, 2.1.1, 2.0.2 > > Attachments: hbase-20705.master.001.patch > > > * Property {{hbase.quota.remove.on.table.delete}} is set to {{true}} by > default > * Create a table and set RPC and Space quota > {noformat} > hbase(main):022:0> create 't2','cf1' > Created table t2 > Took 0.7420 seconds > => Hbase::Table - t2 > hbase(main):023:0> set_quota TYPE => SPACE, TABLE => 't2', LIMIT => '1G', > POLICY => NO_WRITES > Took 0.0105 seconds > hbase(main):024:0> set_quota TYPE => THROTTLE, TABLE => 't2', LIMIT => > '10M/sec' > Took 0.0186 seconds > hbase(main):025:0> list_quotas > TABLE => t2 TYPE => THROTTLE, THROTTLE_TYPE => REQUEST_SIZE, LIMIT => > 10M/sec, SCOPE => MACHINE > TABLE => t2 TYPE => SPACE, TABLE => t2, LIMIT => 1073741824, VIOLATION_POLICY > => NO_WRITES{noformat} > * Drop the table and the Space quota is set to {{REMOVE => true}} > {noformat} > hbase(main):026:0> disable 't2' > Took 0.4363 seconds > hbase(main):027:0> drop 't2' > Took 0.2344 seconds > hbase(main):028:0> list_quotas > TABLE => t2 TYPE => SPACE, TABLE => t2, REMOVE => true > USER => u1 TYPE => THROTTLE, THROTTLE_TYPE => REQUEST_SIZE, LIMIT => 10M/sec, > SCOPE => MACHINE{noformat} > * Recreate the table and set Space quota back.
