HBase server aborts on coprocessor exceptions even though hbase.coprocessor.abortonerror is set to false

[Steen Manniche <bo...@gmail.com>]

I'm trying to specify some sanity checks in my coprocessor's start()
method, throwing exceptions if the checks fail. I have tried throwing
IllegalArgumentException and CoprocessorException from the start
method, but on the client side (a junit test), all I get is a
RuntimeException with no traces of the original exception.

On top of this, the regionserver aborts even though I have set the
property hbase.coprocessor.abortonerror to false in hbase-site.xml

I have experimented with this setting in our docker setup as well, and
here the RegionServer aborts as well.

Any thoughts on this?

Best regards,
Steen

Can you take a look at TestMasterCoprocessorExceptionWithRemove to see if
it covers your case ?

If not, can it be modified to exhibit the behavior you described ?

Cheers
