Hi,

If I deploy a Region Observer to a table using HDFS Jar, is it possible to deploy a new version, enable/disable the table to get that new jar hot deployed, without restarting all the region servers?

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.

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

the region is starting. When disabling/enabling the table it will force
all
regions to be re-opened.
