Description

The FSNamesystem.initAuditLoggers() method reads a list of audit loggers from a call to {{ conf.getStringCollection(DFS_NAMENODE_AUDIT_LOGGERS_KEY);}}

What it doesn't do is trim each entry -so if there's a space or newline in the
list, the classname is invalid and won't load, so HDFS wont come out to play.
