DRILL-4964: Drill fails to connect to hive metastore after hive metas⦠â¦tore is restarted unless drillbits are restarted also Changes: For certain methods in DrillHiveMetaStoreClient like getAllDatabases and getAllTables the HiveMetaStoreClient wraps the exception of type MetaException and TException both into MetaException. So in case of connection failure which is thrown as TException it is difficult to categorize at DrillClient level. Hence the fix is to close older connection and reconnect in case of these 2 api's. In all other cases proper set of exceptions are thrown where we can handle each one individually.
