> 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
> Fix For: 2.0.0
>
> 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/
