I am facing a weird problem. I was accessing my HBase tables through an API. Midway during execution I got a RegionNotServing for my table \'x\'. But My HRegionServers were work
I just had this issue and it turned out that a region server was up but not able to be reached for some reason. Rather than try and debug this, I restarted the region server and this fixed everything.
