Change subject: IMPALA-4704: Disallow client connections to imapalad until catalog is received. ...................................................................... Patch Set 1: (1 comment) http://gerrit.cloudera.org:8080/#/c/8202/1//COMMIT_MSG Commit Message: http://gerrit.cloudera.org:8080/#/c/8202/1//COMMIT_MSG@17 PS1, Line 17: this wait time bound, the impalad exits. Because it's hard to time the start-up of processes on multiple machines, short timeouts like this one (it's 10 seconds, if I'm reading correctly) can cause issues. Most Hadoop-related distributed systems (but not all) wait forever or ~hours before they decide to give up. I'm also under the impression that really large catalogs can take a long time to start-up. Do you know if that would trigger? All that said, I'm simply arguing that it's reasonable to make the number of retries infinite here. I look forward to what others will add! -- To view, visit http://gerrit.cloudera.org:8080/8202 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I52b881cba18a7e4533e21a78751c2e35c3d4c8a6 Gerrit-Change-Number: 8202 Gerrit-PatchSet: 1 Gerrit-Owner: Vuk Ercegovac <vercego...@cloudera.com> Gerrit-Reviewer: Philip Zeyliger <phi...@cloudera.com> Gerrit-Comment-Date: Wed, 04 Oct 2017 16:29:40 +0000 Gerrit-HasComments: Yes
