> from the comment and the expected behavior AssignmentManager.assign() should
> be sync
> {code}
> /** Assigns specified regions round robin, if any.
> * This is a synchronous call and will return once every region has been
> public void assign(List<HRegionInfo> regions)
> {code}
> but the code has two path. 1 sync and the async
> {code}
> if (servers == 1 || (regions < bulkAssignThresholdRegions
> && servers < bulkAssignThresholdServers)) {
> for (HRegionInfo region: plan.getValue()) {
> ...
> invokeAssign(region); // <-- this is async threadPool.submit(assign)
> ...
> }
> } else {
> BulkAssigner ba = new GeneralBulkAssigner(...);
> ba.bulkAssign(); // <-- this is sync, calls BulkAssign.waitUntilDone()
> }
> {code}
> https://builds.apache.org/job/HBase-1.1/452/ TestCreateTableProcedure is
> flaky because of this async behavior
