Alexandre Linte resolved HIVE-15050.
------------------------------------
Resolution: Fixed
> Webhcat fails to start with Syslog appender
> -------------------------------------------
>
> Key: HIVE-15050
> URL: https://issues.apache.org/jira/browse/HIVE-15050
> Project: Hive
> Issue Type: Bug
> Components: WebHCat
> Affects Versions: 2.1.0
> Environment: Hive 2.1.0, Hadoop 2.7.2
> Reporter: Alexandre Linte
>
> WebHCat fails to start if SyslogAppender is set instead of a more conventional FileAppender or DailyRollingFileAppender. However, Hive itself can work with a syslog appender.
> The error displayed when the webhcat service is killed is:
> {noformat}
