Jesus Camacho Rodriguez commented on HIVE-16996:
------------------------------------------------

[~pxiong], I am seeing the following warning when I compile the project:
{noformat}
[WARNING] Some problems were encountered while building the effective model for org.apache.hive:hive-exec:jar:3.0.0-SNAPSHOT
[WARNING] 'dependencies.dependency.(groupId:artifactId:type:classifier)' must be unique: javolution:javolution:jar
-> duplicate declaration of version ${javolution.version} @ org.apache.hive:hive-exec:[unknown-version],
/grid/5/dev/jcamachorodriguez/dist/tez-autobuild/hive/ql/pom.xml, line 366, column 17
{noformat}
Might be related to this change? Thanks
