Change subject: [DRAFT] IMPALA-6189: Add thread watchdogs for HDFS IO calls ...................................................................... Patch Set 3: (1 comment) http://gerrit.cloudera.org:8080/#/c/10696/3//COMMIT_MSG Commit Message: http://gerrit.cloudera.org:8080/#/c/10696/3//COMMIT_MSG@20 PS3, Line 20: --thread_watchdog_threshold_ms=0 (default = 5000ms) I wonder if the default threshold is too low, in the sense that we may get a lot of 'false positives' on 'hangs'. The Linux kernel hung task detector has a default timeout of 120 seconds by comparison. -- To view, visit http://gerrit.cloudera.org:8080/10696 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I28e918761c120043d332b034450208eaf34e3e2b Gerrit-Change-Number: 10696 Gerrit-PatchSet: 3 Gerrit-Owner: Bharath Vissapragada <bhara...@cloudera.com> Gerrit-Reviewer: Balazs Jeszenszky <jes...@gmail.com> Gerrit-Reviewer: Bharath Vissapragada <bhara...@cloudera.com> Gerrit-Reviewer: Dan Hecht <dhe...@cloudera.com> Gerrit-Reviewer: Lars Volker <l...@cloudera.com> Gerrit-Reviewer: Zoram Thanga <zo...@cloudera.com> Gerrit-Comment-Date: Thu, 21 Jun 2018 07:00:18 +0000 Gerrit-HasComments: Yes
