[jira] [Commented] (HBASE-20705) Having RPC Quota on a table prevents Space quota to be recreated/removed

["Josh Elser (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-20705?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16514209#comment-16514209 ] 

Josh Elser commented on HBASE-20705:
------------------------------------

{quote}Space quota is set to {{REMOVE => true}}
{quote}
[~gsbiju], where are you getting this syntax from? If you're trying to remove a space quota, you would provide the {{LIMIT => NONE}}
{code:java}
Space quotas can also be removed via this command. To remove a space quota, provide NONE
for the limit.

For example:

  hbase> set_quota TYPE => SPACE, TABLE => 't1', LIMIT => NONE
  hbase> set_quota TYPE => SPACE, NAMESPACE => 'ns1', LIMIT => NONE{code}
