Summary
-------
https://issues.apache.org/jira/browse/HBASE-4014 Coprocessors: Flag the
presence of coprocessors in logged exceptions
The general gist here is to wrap each of {Master,RegionServer}CoprocessorHost's
coprocessor call inside a
"try { ... } catch (Throwable e) { handleCoprocessorThrowable(e) }"
block.
handleCoprocessorThrowable() is responsible for either passing 'e' along to the
client (if 'e' is an IOException) or, otherwise, aborting the service
(Regionserver or Master).
The abort message contains a list of the loaded coprocessors for crash analysis.
This addresses bug HBASE-4014.

Testing

patch includes two tests:
TestMasterCoprocessorException.java

> For some initial triage of bug reports for core versus for deployments with
> loaded coprocessors, we need something like the Linux kernel's taint flag,
> and list of linked in modules that show up in the output of every OOPS, to
> appear above or below exceptions that appear in the logs.
