BELUGA BEHR updated HDFS-14258:
-------------------------------
Status: Patch Available (was: Open)
New patch (and updated git PR)
Since I'm touching a large part of the file, I've gone back and fixed up a
bunch of check-style errors and added a bunch of comments.
If the class is not unable to lower the thread count within 30s, it fails and
returns a boolean to the calling code so that a proper Exception can be thrown.
I am very hesitant to add a new configuration here. Hadoop already has 1,000+
undocumented/under-documented valves to turn.
