Re: java.lang.RuntimeException: [Simba][ImpalaJDBCDriver](500169) Unable to connect to server: null

Can you please enable JDBC driver TRACE log by adding:

;LogLevel=6;LogPath=/tmp/jdbc-log

to the end of JDBC connection string and collect trace log, there might be clues there.

Also, have you checked the impala daemon log on host beta01.opr.test.XYZ.COM to see if there is any error messages related?
