> Key: HBASE-22944
> URL: https://issues.apache.org/jira/browse/HBASE-22944
> Project: HBase
> Issue Type: Bug
> Components: Quotas
> Reporter: Shardul Singh
> Assignee: Shardul Singh
> Priority: Minor
>
> During Master startup if quota feature is enabled and region server is
> running TableNotFoundException occurs in regionServer logs
> SpaceQuotaRefresherChore does not checks whether hbase:quota table is
> present,before starting its operation which sometimes may result to
> TableNotFoundExceptions like below.
> This is because master has not created the hbase:quota table and
> SpaceQuotaRefresherChore is running.
> {code:java}
> java.io.UncheckedIOException: org.apache.hadoop.hbase.
