Michael Ho created IMPALA-8427: ---------------------------------- Summary: Document the behavior change in IMPALA-7800 Key: IMPALA-8427 URL: https://issues.apache.org/jira/browse/IMPALA-8427 Project: IMPALA Issue Type: Documentation Components: Clients Affects Versions: Impala 3.3.0 Reporter: Michael Ho Assignee: Alex Rodoni
IMPALA-7800 changes the default behavior of client connection timeout with HS2 and Beeswax Thrift servers. Quote from the commit message: {noformat} The current implementation of the FE thrift server waits indefinitely to open the new session, if the maximum number of FE service threads specified by --fe_service_threads has been allocated. This patch introduces a startup flag to control how the server should treat new connection requests if we have run out of the configured number of server threads. If --accepted_client_cnxn_timeout > 0, new connection requests are rejected by the server if we can't get a server thread within the specified timeout. We set the default timeout to be 5 minutes. The old behavior can be restored by setting --accepted_client_cnxn_timeout=0, i.e., no timeout. The timeout applies only to client facing thrift servers, i.e., HS2 and Beeswax servers. {noformat} -- 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
