Change subject: IMPALA-6813: Hedged reads metrics broken when scanning non-HDFS based table ...................................................................... Patch Set 3: > preads add some overhead to HDFS, since it sends out redundant read > requests to replicas. Having it on by default might cause some > confusion while running multiple heavy concurrent workloads. You're talking about hedged reads, not preads. We can use pread with hedge reads on or off. So that can't be the blocker. -- To view, visit http://gerrit.cloudera.org:8080/9966 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I48fe80dfd9a1ed68a8f2b7038e5f42b5a3df3baa Gerrit-Change-Number: 9966 Gerrit-PatchSet: 3 Gerrit-Owner: Sailesh Mukil <[email protected]> Gerrit-Reviewer: Dan Hecht <[email protected]> Gerrit-Reviewer: Impala Public Jenkins <[email protected]> Gerrit-Reviewer: Philip Zeyliger <[email protected]> Gerrit-Reviewer: Sailesh Mukil <[email protected]> Gerrit-Reviewer: Tim Armstrong <[email protected]> Gerrit-Comment-Date: Tue, 22 May 2018 23:16:14 +0000 Gerrit-HasComments: No
