BELUGA BEHR commented on HDFS-9457:
-----------------------------------
I updated to include all areas and to make use of SLF4J place holders.
One thing I noticed was inconsistency in reporting exceptions. What do you
think should be done? I will apply in a different ticket.
{code}
LOG.warn("Received exception in Datanode#join: {}", ex);
v.s.
LOG.error("Exception in secureMain", e);
{code}
