Description

Some fall-out from ACCUMULO-4424

The thrift server for the MasterClientServiceHandler is started before we acquire the ZK lock, but access to it is precluded until after we acquire that lock. The problem is that the state of the master is not guaranteed to be fully initialized after that lock is grabbed.

It is simple to add a boolean flag instead after the state in the master is initialized completely.
