> The MetastorePlugin.SyncTask class is a thread running in the background in
> the HMS side that is used to keep HMS/Sentry in sync with HDFS, or any other
> words, it pushes a full HMS snapshot to Sentry every time Sentry is
> out-of-sync.
> However when a timed out exception is thrown when sending the snapshot to
> Sentry, a retry happens in the next thread run() iteration.
> The problem is that these exceptions do not terminate the Thrift thread
> sending the data, and a new retry will generate a new Thrift thread be
> created. We should close those threads by resetting the connection when an
> error occurs.
