Change subject: IMPALA-7528: Fix division by zero when computing cardinalities ...................................................................... Patch Set 4: As it turns out, I tackled this at the root cause (NDV=0) in #11528, IMPALA-7310: Use NDV=1 for a Column with all nulls (Waiting for final review.) Perhaps it is good to tackle the issue in both places: on the metadata side and by being safe when doing calculations. -- To view, visit http://gerrit.cloudera.org:8080/11901 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Ieedd51d3ad6131a4ea2a5883f05104e6a0f2cd14 Gerrit-Change-Number: 11901 Gerrit-PatchSet: 4 Gerrit-Owner: Bikramjeet Vig <bikramjeet....@cloudera.com> Gerrit-Reviewer: Bharath Vissapragada <bhara...@cloudera.com> Gerrit-Reviewer: Bikramjeet Vig <bikramjeet....@cloudera.com> Gerrit-Reviewer: Impala Public Jenkins <impala-public-jenk...@cloudera.com> Gerrit-Reviewer: Paul Rogers <par0...@yahoo.com> Gerrit-Reviewer: Tim Armstrong <tarmstr...@cloudera.com> Gerrit-Comment-Date: Thu, 08 Nov 2018 02:44:52 +0000 Gerrit-HasComments: No
