Joseph updated HBASE-16036:
---------------------------
Description:
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
