> Reporter: Nick Allen
> Assignee: Nick Allen

> I have not been able to configure logging for the REST API. To replicate,
> create a log4j configuration file, then add the following to "Metron JVM
> Flags" in Ambari > Metron > Config.
> {code}
> -Dlog4j.debug
> -Dlog4j.configuration=file:/usr/metron/0.4.2/config/log4j.properties
> {code}
> This will result in the following exception when Log4j initializes.
> {code}
> log4j: Using URL [file:/usr/metron/0.4.2/config/log4j.properties] for
> automatic log4j configuration.
> log4j: Reading configuration from URL
> file:/usr/metron/0.4.2/config/log4j.properties
> log4j: Parsing for [root] with value=[INFO, file].
> log4j: Level token is [INFO].
> log4j: Category root set to INFO
> log4j: Parsing appender named "file".
> log4j:ERROR A "org.apache.log4j.RollingFileAppender" object is not assignable
> to a "org.apache.hadoop.hbase.shaded.org.apache.log4j.Appender" variable.
> log4j:ERROR The class
> "org.apache.hadoop.hbase.shaded.org.apache.log4j.Appender" was loaded by
> log4j:ERROR [sun.misc.Launcher$AppClassLoader@5c647e05] whereas object of type
> log4j:ERROR "org.apache.log4j.RollingFileAppender" was loaded by
> [sun.misc.Launcher$AppClassLoader@5c647e05].
> log4j:ERROR Could not instantiate appender named "file".
> log4j: Finished configuring.
