> It seems that alert is checking wrong port (10016 instead of 10002) when
> configured in http mode (transportMode=http).
> Reason
> =====
> From the logic in the script it seems that if the transport mode is binary it
> will use HIVE_SERVER_THRIFT_PORT which is same as of THRIFT_PORT_DEFAULT.
> Hence it will always go for 10016 port.
> ============
> THRIFT_PORT_DEFAULT = 10016
> HIVE_SERVER_TRANSPORT_MODE_DEFAULT = 'binary'
> port = THRIFT_PORT_DEFAULT
> if transport_mode.lower() == 'binary' and HIVE_SERVER_THRIFT_PORT_KEY in
> configurations:
> port = int(configurations[HIVE_SERVER_THRIFT_PORT_KEY])
> ========
> Resolution
> We should change the default port to 10002 in the alert script.
