Major Description
Currently webhcat log files are full of exceptions like this, which obscures the real output and may cause perf issues.
Upgrading to more recent versions of xerces/xalan fixes this.
Add the following to hive/hcatalog/webhcat/svr/pom.xml
<dependency>
<groupId>xerces</groupId>
<artifactId>xercesImpl</artifactId>
<version>2.9.1</version>
