Hi Guy, I can't say if that is reasonable without more info. How are you running datanodes, namenodes and zookeepers? Also, what are the JVM options for each process? Can you share your dockerfiles? What OS are you on? How much of your OS can Docker take? What is the data in your benchmark_table?
Like Sean mentioned, running multiple tservers will help to distribute the load. You may or may not have headroom. It is possible to run multiple tservers on the same host, even without docker. Like Jeremy mentioned, I have seem better performance than you are getting on a single node cluster but I usually use the standalone mini accumulo for that, not a full cluster setup with HDFS.
