> Key: HADOOP-7577
> URL: https://issues.apache.org/jira/browse/HADOOP-7577
> Project: Hadoop Common
> Issue Type: Bug
> Components: metrics
> Affects Versions: 0.22.0
> Reporter: Joep Rottinghuis
> Assignee: Joep Rottinghuis
> Priority: Minor
>
> Between metrics1 and mertrics2 EventCounter was moved from o.a.h.log to
> o.a.h.metrics.jvm.
> On 0.20-security a wrapper marked with @Deprecated was added back to
> o.a.h.log for compatibility, the same wrapper exists on trunk, but no on 0.22.
> Without it the TT will fail to start with a ClassNotFoundException.
> Hive configuration also point to this class in the log4j.properties.
