Summary: Procedure V2 - Distributed Log Splitting
Key: HBASE-20610
URL: https://issues.apache.org/jira/browse/HBASE-20610
Project: HBase
Issue Type: Umbrella
Components: proc-v2
Reporter: Guanghao Zhang
Fix For: 3.0.0
Now master and regionserver use zk to coordinate log split tasks. The split log
manager manages all log files which need to be scanned and split. Then the
split log manager places all the logs into the ZooKeeper splitWAL node
(/hbase/splitWAL) as tasks and monitors these task nodes and waits for them to
be processed. Each regionserver watch splitWAL znode and grab task when node
children changed. And regionserver does the work to split the logs.
Open this umbrella issue to move this "coordinate" work to use new procedure v2
framework and reduce zk depencency. Plan to finish this before 3.0 release. Any
suggestions are welcomed. Thanks.
