For example when an INSERT OVERWRITE statement updates the > majority of the partitions and only drops few of them. Will this case not introduce inconsistency between HMS and Impala? -- To view, visit http://gerrit.cloudera.org:8080/10450 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Iaabdf38af3f30c65ada9734eb471dbfa6ecdd74a Gerrit-Change-Number: 10450 Gerrit-PatchSet: 2 Gerrit-Owner: Pranay Singh Gerrit-Reviewer: Alex Behm <alex.b...@cloudera.com> Gerrit-Reviewer: Bharath Vissapragada <bhara...@cloudera.com> Gerrit-Reviewer: Pranay Singh Gerrit-Reviewer: Quanlong Huang <huangquanl...@gmail.com> Gerrit-Comment-Date: Sat, 19 May 2018 18:15:20 +0000 Gerrit-HasComments: No
