> {{ambari-common/src/main/python/resource_management/libraries/functions/hive_check.py}}
uses a combination of {{beeline}} and sockets to check the availability of the Hive server.
> Hive Server can be configured to run in either {{binary}} or {{http}} mode, as configured
by the following property in {{hive-site}}:
> {code}
>     <property>
>       <name>hive.server2.transport.mode</name>
>       <value>binary</value>
>     </property>
> {code}
> The python, however, only runs the {{beeline}} command if KERBEROS is in use _AND_ the
mode is {{binary}}. This not correct in that {{beeline}} can connect via both TCP and HTTP:
> {code}
> beeline -u 'jdbc:hive2://c6402.ambari.apache.org:10000/;transportMode=binary' -e ''
> beeline -u 'jdbc:hive2://c6402.ambari.apache.org:10001/;transportMode=http' -e ''
> {code}
> Additionally, {{alert_hive_thrift_port.py}} needs to provide a better error message.
Currently, the code
> {code}
>     try:
>       hive_check.check_thrift_port_sasl(host_name, port,
>         hive_server2_authentication, hive_server_principal, kinitcmd, smokeuser,
>         transport_mode = transport_mode)
>       is_thrift_port_ok = True
>     except:
>       is_thrift_port_ok = False
>     if is_thrift_port_ok == True:
>       result_code = 'OK'
>       total_time = time.time() - start_time
>       label = OK_MESSAGE % (total_time, port)
>     else:
>       result_code = 'CRITICAL'
>       label = CRITICAL_MESSAGE.format(host_name,port)
> {code}
> will not show the exact error message and instead just say that it couldn't connect to
host:port, which is wrong since that implies the only failure could be TCP-based. I recommend
putting the exception message in as well.
