ASF subversion and git services commented on IMPALA-8701: --------------------------------------------------------- Commit 1c9af2cb526b038c080f1b09acc403e8d7378364 in impala's branch refs/heads/master from Alex Rodoni [ https://gitbox.apache.org/repos/asf?p=impala.git;h=1c9af2c ] IMPALA-8701: [DOCS] Document --idle_client_poll_time_s flag Change-Id: I32ace786904f564b9c5fa3ed594e2b679b76d5c6 Reviewed-on: http://gerrit.cloudera.org:8080/13896 Tested-by: Impala Public Jenkins <impala-public-jenk...@cloudera.com> Reviewed-by: Michael Ho <k...@cloudera.com> > Document idle session management after IMPALA-7802 > -------------------------------------------------- > > Key: IMPALA-8701 > URL: https://issues.apache.org/jira/browse/IMPALA-8701 > Project: IMPALA > Issue Type: Task > Components: Docs > Affects Versions: Impala 3.3.0 > Reporter: Michael Ho > Assignee: Alex Rodoni > Priority: Major > Labels: future_release_doc, in_33 > Fix For: Impala 3.3.0 > > > After IMPALA-7802 is fixed, the network connection of an idle session will be > closed {{\-\-idle_client_poll_time_s}} seconds latest after the session has > been declared idle. This is a change of behavior from previous versions in > which the client connection will hang around until the user explicitly closes > the session and disconnects. > By default, {{\-\-idle_client_poll_time_s}} is set to 30 seconds and the > previous behavior can be restored by setting to 0. In addition, the session > will only be closed if idle session timeout has been configured to be greater > than 0 for the session either via the startup flag {{--idle_session_timeout}} > or the query option {{IDLE_SESSION_TIMEOUT}}. If idle session timeout is not > configured, a session cannot become idle by definition and therefore its > connection cannot be closed until the client explicitly closes it. -- This message was sent by Atlassian JIRA (v7.6.14#76016) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
