We should do as Gary suggests anyways. > Cache table state to reduce load on META > ---------------------------------------- > > Key: HBASE-16025 > URL: https://issues.apache.org/jira/browse/HBASE-16025 > Project: HBase > Issue Type: Improvement > Components: Client > Reporter: Gary Helmling > Assignee: Gary Helmling > Priority: Blocker > Fix For: 2.0.0 > > > HBASE-12035 moved keeping table enabled/disabled state from ZooKeeper into hbase:meta. When we retry operations on the client, we check table state in order to return a specific message if the table is disabled. This means that in master we will be going back to meta for every retry, even if a region's location has not changed. This is going to cause performance issues when a cluster is already loaded, ie. in cases where regionservers may be returning CallQueueTooBigException. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
