Joseph updated HBASE-16036: --------------------------- Attachment: HBASE-16036.patch > Fix ReplicationTableBase initialization to make it non-blocking > --------------------------------------------------------------- > > Key: HBASE-16036 > URL: https://issues.apache.org/jira/browse/HBASE-16036 > Project: HBase > Issue Type: Sub-task > Components: Replication > Reporter: Joseph > Assignee: Joseph > Attachments: HBASE-16036.patch > > > Currently there is a bug inside of TableBasedReplicationQueuesImpl > construction that prevents ReplicationServices from starting before Master is > initialized. So currently each of the RS, including HMaster, with Replication > enabled will attempt to create the ReplicationTable on initialization. > Currently HMaster's initialization: serviceThreads.start() -> new > TableBasedReplicationQueuesImpl() -> Replication Table Creation -> HMaster > sets initialized flags. > But this fails when we try to create the Replication Table as the > HMaster.checkInitialized() flag fails. This ends up blocking HMaster > initialization and results in a deadlock. > So in this patch, I will create the Replication Table in the background of > TableBasedReplicationQueuesImpl and only block when we actually call methods > that access it. > This also requires a small refactoring of ReplicationSourceManager.init() so > that we run the abandoned queue adoption in the background > Review board at: https://reviews.apache.org/r/48763/ -- This message was sent by Atlassian JIRA (v6.3.4#6332)
