With prefetch-on-open enabled, the task doing the prefetching was using
non-positional (i.e. streaming) reads. If the main (non-prefetch) thread
was also using non-positional reads, these two would conflict, because
inputstreams are not thread-safe for non-positional reads.
In the case of an encrypted filesystem, this could cause JVM crashes,
etc, as underlying cipher buffers were freed underneath the racing
threads. In the case of a non-encrypted filesystem, less severe errors
would be thrown. The included unit test reproduces the latter case.

Also changes modify table operations to help the case where a MTP spans
two master, avoiding the sanity-checks propagating back to the client
unnecessarily.

ModifyTableProcedure is using MoveRegionProcedure in a way
that was unintended from the original implementation. As such,
we have to guard against certain usages of it. We know we can
re-open OPEN regions, but regions in OPENING will similarly
soon be OPEN (thus, we want to reopen those regions too).

Provides an extra client descriptor to build a second
tarball with a reduced set of dependencies. Not of great
impact now, but will build the way for better in the future.

* modify the jar checking script to take args; make hadoop stuff optional
* separate out checking the artifacts that have hadoop vs those that don't.
* * Unfortunately means we need two modules for checking things
* * put in a safety check that the support script for checking jar contents is maintained in both modules
* * have to carve out an exception for o.a.hadoop.metrics2. :(
* fix duplicated class warning
* clean up dependencies in hbase-server and some modules that depend on it.
* allow Hadoop to have its own htrace where it needs it
* add a precommit check to make sure we're not using old htrace imports

HBase ITs require junit which requires hamcrest. Hadoop recently
stopped including hamcrest in their installation (and thus our inherited
classpath), which means that we need to ship it.
