  Several of these conditions become more common in VM environments, where they
  can be exacerbated by resource constraints and clock drift.
  
- Accumulo includes a mechanism to limit the impact of the false positives known
- as the <<watcher>>. The watcher monitors Accumulo processes and will restart
- them when they fail for certain reasons. The watcher can be configured within
- the accumulo-env.sh file inside of Accumulo's configuration directory. We
- recommend using the watcher to monitor Accumulo processes, as it will restore
- the system to full capacity without administrator interaction after many of the
- common failure modes.

  ==== Tested Versions
 -Another large consideration for Accumulo stability is to use versions of
 -software that have been tested together in a VM environment. Any cluster of
 -processes that have not been tested together are likely to expose running
 -conditions that vary from the environments individually tested in the various
 -components. For example, Accumulo's use of HDFS includes many short block
 -reads, which differs from the more common full file read used in most
 -map/reduce applications. We have found that certain versions of Accumulo and
 -Hadoop will include stability bugs that greatly affect overall stability. In
 -our testing, Accumulo 1.6.2, Hadoop 2.6.0, and Zookeeper 3.4.6 resulted in a
 -stable VM clusters that did not fail a month of testing, while Accumulo 1.6.1,
 -Hadoop 2.5.1, and Zookeeper 3.4.5 had a mean time between failure of less than
 -a week under heavy ingest and query load. We expect that results will vary with
 -other configurations, and you should choose your software versions with that in
 -mind.

 +Each release of Accumulo is built with a specific version of Apache
 +Hadoop, Apache ZooKeeper and Apache Thrift.  We expect Accumulo to
 +work with versions that are API compatable with those versions.
 +However this compatibility is not guaranteed because Hadoop, ZooKeeper
 +and Thift may not provide guarantees between their own versions. We
 +have also found that certain versions of Accumulo and Hadoop included
 +bugs that greatly affected overall stability.  Thrift is particularly
 +prone to compatablity changes between versions and you must use the
 +same version your Accumulo is built with.
 +
 +Please check the release notes for your Accumulo version or use the
 +mailing lists at https://accumulo.apache.org for more info.
