Cloudera Manager - Impala Query UI "Time out"

If you are running a big Imapla query in Cloudera Manager's Impala Query UI (Hue) and getting a "Time Out" error, you can try to increase the "beeswax_server_conn_timeout" in "Hue" -> "Beeswas Server (Default)". This "beeswax_server_conn_timeout" defines the Timeout in seconds for Thrift calls to the Beeswax service. In Impala documentation, it is mentioned that Impala shares the same user interface with Apache Hive (Hue Beeswax). So increase the "beeswax_server_conn_timeout" value would probably solve the "timeout" problem.
