Change subject: IMPALA-6538: Fix read path when Parquet min/max statistics contain NaN ...................................................................... IMPALA-6538: Fix read path when Parquet min/max statistics contain NaN If the first number in a row group written by Impala is NaN, then Impala writes incorrect statistics in the metadata. This will result in incorrect results when filtering the data. This commit fixes the read path when encountering NaNs in Parquet min/max statistics. If max is NaN, then Impala will interpret it as infinity. If min is NaN, then -infinity will be used. I added some tests to QueryTest/parqet-stats.test Change-Id: If3897fc1426541239223670812f59e2bed32f455 --- M be/src/exec/parquet-column-stats.cc M testdata/workloads/functional-query/queries/QueryTest/parquet-stats.test 2 files changed, 48 insertions(+), 4 deletions(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/58/9358/1 -- To view, visit http://gerrit.cloudera.org:8080/9358 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: newchange Gerrit-Change-Id: If3897fc1426541239223670812f59e2bed32f455 Gerrit-Change-Number: 9358 Gerrit-PatchSet: 1 Gerrit-Owner: Zoltan Borok-Nagy <borokna...@cloudera.com>
