> In HIVE-9253, we add a timeout mechanism in HMS. We start the timer in RetryingHMSHandler.invoke,
and then -> RawStoreProxy.invoke -> ObjectStore.xxxMethod. The timer is stopped after
methods complete.
> It was found that, the methods of ObjectStore might be invoked directly in o.a.h.h.ql.txn.compactor.CompactorThread,
but not throught HMSHandler. This will cause timeout checking to throw exception. We need
fix this bug here.
