@cgivre My PR uses the latest Spark code for the SizeEstimator as opposed to very old copy of the Spark code that was copied and not maintained in java-sizeof lib. The new code gives slightly higher estimates for object instance sizes. Would this be an issue? Also, with tests - Spark and the java-sizeof lib use some Scala based tests - and they are not that easily replicated in Java. The question is whether the tests that I've added in this PR or if I need more. |

Given that this only affects the OpenTSDB plugin, I think it is fine. I've honestly never even heard of anyone actually using that with Drill. |
