DRILL-4964: Drill fails to connect to hive metastore after hive metasâ¦
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.
