Change subject: IMPALA-6035: Add query options to limit thread reservation ...................................................................... Patch Set 9: (1 comment) http://gerrit.cloudera.org:8080/#/c/10365/9/common/thrift/ImpalaInternalService.thrift File common/thrift/ImpalaInternalService.thrift: http://gerrit.cloudera.org:8080/#/c/10365/9/common/thrift/ImpalaInternalService.thrift@287 PS9, Line 287: 66: optional i32 thread_reservation_limit = 0; Dan suggested setting a default here. I started doing some experiments to see what our current practical limits are. On stock Ubuntu 16.04 I start getting thread_resource_error at around 8000 reserved threads. I'm not sure that the config reflects what people would use on production systems so continuing to investigate. -- To view, visit http://gerrit.cloudera.org:8080/10365 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I5b5bbbdad5cd6b24442eb6c99a4d38c2ad710007 Gerrit-Change-Number: 10365 Gerrit-PatchSet: 9 Gerrit-Owner: Tim Armstrong <[email protected]> Gerrit-Reviewer: Bikramjeet Vig <[email protected]> Gerrit-Reviewer: Dan Hecht <[email protected]> Gerrit-Reviewer: Mostafa Mokhtar <[email protected]> Gerrit-Reviewer: Tim Armstrong <[email protected]> Gerrit-Comment-Date: Fri, 01 Jun 2018 20:11:47 +0000 Gerrit-HasComments: Yes
