> Suppress callstack in LOG.warn() when we add a datanode to deadnode list
> -------------------------------------------------------------------------

> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: hdfs
> Reporter: Xing Lin
> Assignee: Xing Lin
> Priority: Trivial
> Labels: pull-request-available

> Right now, we print the callstack whenever we add a datanode to deadnodes.
> Whenever a user sees a couple of these callstacks, they would think hdfs is
> having some issue, thus reaching out to HDFS team oncall for trouble
> shooting. We should suppress the callstack for these non-fatal retriable
> errors.
