Joe McDonnell created IMPALA-13229: -------------------------------------- Summary: Improve logging for TAcceptQueueServer when a thread takes a long time in SASL negotiation Key: IMPALA-13229 URL: https://issues.apache.org/jira/browse/IMPALA-13229 Project: IMPALA Issue Type: Task Components: Backend Affects Versions: Impala 4.4.0 Reporter: Joe McDonnell
In IMPALA-11653, we are concerned about bad clients that use up threads in the SASL negotiation thread pool for long periods of time (or eventually hit sasl_connect_tcp_timeout_ms). As a separate task, it would be useful to be able to quickly tell from the logs whether a connection spends a lot of time in the SASL negotiation and could be creating this type of problem. We should add some logging to make this issue clear from the logs. One option is to log a warning if SASL negotiation takes longer than some threshold (and thus was using up a thread during that time). If SASL negotiation is taking longer than a few seconds, that can be a real issue. -- This message was sent by Atlassian Jira (v8.20.10#820010)
