Thanks, Eugene. Almost there I think! Just a couple comments on the tests.
src/main/java/org/apache/hadoop/hbase/coprocessor/CoprocessorHost.java
<https://reviews.apache.org/r/969/#comment4147>
This should default to false.
src/test/java/org/apache/hadoop/hbase/coprocessor/TestMasterCoprocessorException.java
<https://reviews.apache.org/r/969/#comment4192>
Does this need to be a separate thread? Can the contents of the run()
method just be inline in testExceptionFromCoprocessorWhenCreatingTable()?
src/test/java/org/apache/hadoop/hbase/coprocessor/TestMasterCoprocessorException.java
<https://reviews.apache.org/r/969/#comment4193>
Do we need this test? If we're already doing the same tests in
TestMasterObserver, it doesn't seem like it. Has anything been added to this
method that we need?
src/test/java/org/apache/hadoop/hbase/coprocessor/TestRegionServerCoprocessorException.java

Name should be something like testExceptionDuringPut?

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