Testing Coprocessor Methods postSplit() and postWALRestore()
Hi everyone,
I'm working on building unit tests for a Coprocessor class I'm building
with HBase for a Lucene search index.
In writing the unit tests, I can't seem to figure out how to call/test
postSplit() and postWALRestore() from the HBase API.
Specifically, all of the implementations of splitting a region I've run
into have been asynchronous and do not complete (I test with a while loop
checking for increased number of regions)
and I can't think of a way to crash and bring up an HBase Region (Only
close and open, not reopen). If there are classes to create synchronous
splits and crash/reopen an HBase Region, would greatly appreciate the
advice. Thanks!
Cheers,
Kevin

Using HBase 0.92.1 and the unit test is using HBaseTestingUtility and
creating mini clusters for testing. Thanks!

What version of HBase are you using ?
Thanks

What if you just stood up a lone HRegion? See TestHRegion for
examples of how to do it. You should be able to then invoke the
HRegion methods directly?
