https://github.com/apache/flink/pull/4110
yes it is still required, but this PR does address a similar issue.
#4109 limits the size of the operator name in the metric identifier. This
was a problem for all reporters, because a 200+ character name just isn't
manageable.
This PR limits the size of all components of the metric identifier for
DropwizardReporters, as the backends of several subclasses store metrics in
files, with each component being one directory., like
"taskmanager/abcde/job/myjob/task/mytask". Since they are used as names for
directories they mustn't exceed a certain size (commonly 255). While
technically a value close to 255 would suffice, i figure that anything above 80
characters isn't really well manageable as well.
