Tim Armstrong updated IMPALA-1653: ---------------------------------- Issue Type: New Feature (was: Bug) > Impala should not close a session when a HiveServer2 connection is closed > ------------------------------------------------------------------------- > > Key: IMPALA-1653 > URL: https://issues.apache.org/jira/browse/IMPALA-1653 > Project: IMPALA > Issue Type: New Feature > Components: Clients > Affects Versions: Impala 2.1 > Reporter: Erick Tryzelaar > Priority: Minor > Labels: ramp-up > > Hue is currently [stateful|https://issues.cloudera.org/browse/HUE-2530] > because in [IMPALA-564|https://issues.cloudera.org/browse/IMPALA-564], Impala > will close the session if the connection is closed. Among other things, this > prevents us from stateless load balancing because we need to route users to > the same Hue backend that holds open the Impala socket. > According to the [HiveServer2 design > document|https://cwiki.apache.org/confluence/display/Hive/HiveServer2+Thrift+API], > the HS2 protocol allows for the session to independent from the connection. > Adding supporting this might not be too difficult. The connection is > explicitly closed > [here|https://github.com/cloudera/Impala/blob/master/be/src/service/impala-server.cc#L1696-L1702], > and it's possible removing this block for HS2 connections might be > sufficient to enable this feature. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
