> 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.
