Re: JDBC/beeline client hangs with HiverServer2 (0.13.1)

  By default the sasl auth is enabled, you don't need to set 'auth=noSasl'
unless you configured non-sasl auth.
What errors did you see in the server log initially when noSasl option was
not passed ?

thanks
Prasad

Re: JDBC/beeline client hangs with HiverServer2 (0.13.1)

Posted by Prasad Mujumdar <pr...@cloudera.com>.
   Looks like the connection is successful when you don't set
"auth=noSasl", which is expected. You don't need to set that property in
normal configuration.
Not sure why the 'show table' is failing. Do you see any errors in the
HiveServer2 log ?

thanks
Prasad

RE: JDBC/beeline client hangs with HiverServer2 (0.13.1)

Posted by "Atul Paldhikar (apaldhik)" <ap...@cisco.com>.
Hi Andrew,

Yes I did look at the below Wiki page earlier. I didn’t modify any default settings for HiveServer2 so the hive.server.authentication is “NONE” at this point (which probably results to “SASL” by default I guess).

Also if you look at the beeline output, it is able to connect to HiveServer2 but not giving any response for the query “show tables”.

Thanks

Hi Atul,

The setting you pasted is for the metastore's authentication (setting to false means SASL is disabled there). The setting you want is:



hive.server2.authentication – Authentication mode, default NONE. Options are NONE, NOSASL, KERBEROS, LDAP, PAM and CUSTOM.
