https://community.cloudera.com/t5/Support-Questions/Hive-server-fails-to-connect/m-p/176759#M139009 <P>We recently started using Tableau and allowed Tableau online to access our hive server. Now, from that point, for about 2 hours in morning 10 to 12, our hive queries fail with </P><PRE>Connecting to jdbc:hive2://ip-xxx-xx-x-xxx.ap-south-1.compute.internal:10000/default Unknown HS2 problem when communicating with Thrift server. Error: Could not open client transport with JDBC Uri: jdbc:hive2://ip-xxx-xx-x-xxx.ap-south-1.compute.internal:10000/default: java.net.SocketException: Connection reset (state=08S01,code=0) No current connection Intercepting System.exit(2) Failing Oozie Launcher, Main class [org.apache.oozie.action.hadoop.Hive2Main], exit code [2]</PRE><P> If I try to connect manually, I can connect fine: </P><PRE>beeline -u jdbc:hive2://xxx-xx-x-xxx:10000/ </PRE><P>I then have to take off tableau whitelisted IP and after about 10 minutes,</P><P> it comes back up. We do not have a lot of queries on Tableau. What could be the issue? I have taken off limit to accept connections from zookeeper just in case it had anything to do with it. Pointers?</P> Sat, 01 Sep 2018 13:51:47 GMT teamwebocity 2018-09-01T13:51:47Z
