Hive DDL command failures when submitted via WebHCat are not visible

Consider test Hive_UTF8 in utf8.conf added in HIVE-9272.
If the create table statement there uses column "row" w/o quotes, the command fails since row is a reserved keyword. But all WebHCat reports is exitValue=64. The parser exception that you see running the same command in HiveCLI is nowhere to be found.
