stack commented on HBASE-20610: ------------------------------- [~tianjingyun] Will do sir. Nice-looking feature! > 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 > Priority: Major > Fix For: 3.0.0 > > Attachments: HBASE-20610.master.001.patch > > > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
