Change subject: [docs] Add "one client only" best practice for kudu-spark ...................................................................... Patch Set 1: (1 comment) http://gerrit.cloudera.org:8080/#/c/11409/1/docs/developing.adoc File docs/developing.adoc: http://gerrit.cloudera.org:8080/#/c/11409/1/docs/developing.adoc@230 PS1, Line 230: To diagnose multiple `KuduClient` instances in a Spark job, look for signs in : the logs of the master being overloaded by many `GetTableLocations` or : `GetTabletLocations` requests coming from different clients, usually around the : same time > Is there any manifestation of this issue visible from the operator's side? No, this issue is the problem with having multiple Kudu clients. Unfortunately, it's hard to see from the Spark side except as slowness and errors due to the master being overwhelmed by bursts of client metadata RPCs. -- To view, visit http://gerrit.cloudera.org:8080/11409 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: kudu Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Ibaf369315b8627674ba64e6418d153568ded6fe8 Gerrit-Change-Number: 11409 Gerrit-PatchSet: 1 Gerrit-Owner: Will Berkeley <[email protected]> Gerrit-Reviewer: Alexey Serbin <[email protected]> Gerrit-Reviewer: Andrew Wong <[email protected]> Gerrit-Reviewer: Dan Burkert <[email protected]> Gerrit-Reviewer: Will Berkeley <[email protected]> Gerrit-Comment-Date: Mon, 10 Sep 2018 18:15:15 +0000 Gerrit-HasComments: Yes
