Change subject: IMPALA-12264: Add limit on number of HS2 sessions per user. ...................................................................... Patch Set 1: CDPD-58529 / IMPALA-12264 requests that we should “prevent a rogue application from repeatedly connecting to and monopolizing Impala”, and suggests “we can add configurations to limit concurrent connections”. The structure of thrift is such that it is hard to limit actual connections. For now the plan is to limit the number of HS2 sessions per user. This is a fairly straightforward change that I believe implements the main idea which is to prevent rogue applications as the jira says. As with some other features (e.g. -disconnected_session_timeout) this is just implemented for HiveServer2. As Beeswax is now deprecated it is suggested that customers disable beeswax access for clients by setting the --beeswax_port (Impala Daemon Beeswax Port) flag to 0. -- To view, visit http://gerrit.cloudera.org:8080/21128 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Idd28edc352102d89774f6ece5376e7c79ae41aa8 Gerrit-Change-Number: 21128 Gerrit-PatchSet: 1 Gerrit-Owner: Andrew Sherman <[email protected]> Gerrit-Reviewer: Abhishek Rawat <[email protected]> Gerrit-Reviewer: Andrew Sherman <[email protected]> Gerrit-Reviewer: Impala Public Jenkins <[email protected]> Gerrit-Reviewer: Quanlong Huang <[email protected]> Gerrit-Comment-Date: Wed, 13 Mar 2024 01:10:12 +0000 Gerrit-HasComments: No
