> Testing, I noticed that if we use the HConnection executor service as opposed to the executor service that is created when you create an HTable without passing in a connection: i.e
> HConnectionManager.createConnection(config).getTable(tableName)
> vs
> HTable(config, tableName)
> ... then we will spin up the max 256 threads and they will just hang out though not being used.
> We are encouraging HConnection#getTable over new HTable so worth fixing.
