I think there's a missing property in pxf-profile.xml check if you have <metadata> property under Hive profile

this is newly added profile and if you were using a legacy build it might not have it. <profile> <name>Hive</name> <description>This profile is suitable for using when connecting to Hive</description> <plugins> <fragmenter>org.apache.hawq.pxf.plugins.hive.HiveDataFragmenter</fragmenter> <accessor>org.apache.hawq.pxf.plugins.hive.HiveAccessor</accessor> <resolver>org.apache.hawq.pxf.plugins.hive.HiveResolver</resolver> <metadata>org.apache.hawq.pxf.plugins.hive.HiveMetadataFetcher</metadata> </plugins> </profile>
