Erik Krogen commented on HDFS-10713:
------------------------------------
In HDFS-10475 we hope to add more detailed metrics for which calls are causing
long held locks. We are actively working on this so it should hopefully subsume
any useful information that would be gathered by keeping all of the stack
traces.

> The NameNode logs a message if the FSNamesystem write lock is held by a
> thread for over 1 second. These messages can be throttled to at one most one
> per x minutes to avoid potentially filling up NN logs. We can also log the
> number of suppressed notices since the last log message.
