Subject Re: question regarding HBASE-7351

I am guessing that HBASE-7351 won’t work for my case since process won’t be able to read
the script from disk.

in all requests to that region server failing. Currently, I use zookeeper client to delete
the corresponding znode manually to initiate the recovery process. It will take some time
to figure out the hardware issue and fix it. Meanwhile, I am looking to find some solution
to automate the recovery process.
