> It appears that if an HDFS space quota is set on a target directory for log aggregation
and the quota is already exceeded when log aggregation is attempted, zero-byte log files will
be written to the HDFS directory, however NodeManager logs do not reflect a failure to write
the files successfully (i.e. there are no ERROR or WARN messages to this effect).
> An improvement may be worth investigating to alert users to this scenario, as otherwise
logs for a YARN application may be missing both on HDFS and locally (after local log cleanup
is done) and the user may not otherwise be informed.
> Steps to reproduce:
> * Set a small HDFS space quota on /tmp/logs/username/logs (e.g. 2MB)
> * Write files to HDFS such that /tmp/logs/username/logs is almost 2MB full
> * Run a Spark or MR job in the cluster
> * Observe that zero byte files are written to HDFS after job completion
> * Observe that YARN container logs are also not present on the NM hosts (or are deleted
after yarn.nodemanager.delete.debug-delay-sec)
> * Observe that no ERROR or WARN messages appear to be logged in the NM role log
