Andrew Wang updated HDFS-7411:
------------------------------
    Attachment: hdfs-7411.007.patch

Here's a new patch addressing Colin's review feedback:

* Got rid of the nodes.per.interval config key and instead use blocks.per.interval. I didn't
bother with a DeprecationDelta because the keys are semantically different and can't just
be aliased. Not sure if there's more to do here.
* Added support for "0 means unlimited" for the max.concurrent.tracked.nodes property
* Fixed typos, spacing, added additional debug logging requested. The "every 30 minute print"
since we print out the first insufficiently block encountered while checking each node.
* Fixed a small OBO in the rate limiting, and added a test for the limiting
