Jide created HIVE-29659:
---------------------------
Summary: DoubleColumnStatsMerger.setHighValue writes to lowValue
field instead of highValue
Key: HIVE-29659
URL: https://issues.apache.org/jira/browse/HIVE-29659
Project: Hive
Issue Type: Bug
Components: Metastore
Reporter: Jide
DoubleColumnStatsMerger.setHighValue() calls
aggregateData.setLowValue(highValue) instead of
aggregateData.setHighValue(highValue). This causes the merged maximum value to
overwrite the minimum field, resulting in min > max after merge. The bug was
undetected because the native Hive Metastore writes to a JDO database that does
not validate min <= max.
