Re: Coprocessor HDFS jar hot deployment

[Wei Tan <wt...@us.ibm.com>]

Thanks. I may try this approach later.
Now I am using a remote cluster to test and I have this workaround:

mvn install and skip test
copy the cp to the remote cluster
mvn install with test

I doubt if it is a good approach but it works.


Best Regards,
Wei

Yes of course ; CP is instantiated (and start() method is then called) 
when
the region is starting. When disabling/enabling the table it will force 
all
regions to be re-opened.
