Great! Please include me in your recoverLease() investigations. I'll try
to help out however possible.

My RW testing went well enough, and I didn't see failures until the cluster
hung up.ACCUMULO-3818 is a test issue, and not a problem with accumulo.
I was able to build 1.7.0 from the source tarball.
I'll continue to investigate the recoverLease issue.

In some of my testing on HDFS 2.6.0 and agitation, I believe leases
weren't being recovered until the datanode was restarted (which agitation
killed). Every time I jstack'ed the master, I saw it hung on the HDFS
recoverLease() method. I saw nothing that suggested a bug in Accumulo (a
nod towards Christopher's assessment).

Can you quantify "Some lease recoveries taking a long time in HDFS."?
I think Keith and I are ok with the release. We're looking into our
(shared) testing environment to figure out why Accumulo and HDFS are not
getting along during recoveries.

Repeatedly ran into issues with HoldTime from HDFS (wrote a loop to just
restart the ingester). Some lease recoveries taking a long time in HDFS.
Nothing super impactful.
I believe that wraps up all required testing.
