Mingliang Liu commented on HDFS-9457:
-------------------------------------
Thanks for your further effort.
I meant to remove {{if (LOG.isTraceEnabled())}} by saying
{quote}
...we should remove guards when calling {{LOG.debug()}}...
{quote}
I think the trace message is not depending on the LOG tracing level.
