Summary: Remove Master from table status query path. Key: HBASE-12203 URL: https://issues.apache.org/jira/browse/HBASE-12203 Project: HBase Issue Type: Improvement Components: Client, master Affects Versions: 2.0.0 Reporter: Andrey Stepachev Fix For: 1.0.0, 2.0.0 With patch HBASE-7767 we moved table statuses from ZK to HDFS. That was a good cleanup, but we put additional (substantial) load on master. Some client requests use checks for table state (for example HBASE-12035). Thats is why patch was not back ported to branch1 (HBASE-11978) Lets replicate state back to zk, but as a mirror of table states. What can be done: 1. TableStateManager would push table state changes to zk 2. Return back ZKTableStateClientSideReader. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
