> *Problem description*
> For the case when the exception was thrown during [initializing {{RootExec root}}|https://github.com/apache/drill/blob/master/exec/java-exec/src/main/java/org/apache/drill/exec/work/fragment/FragmentExecutor.java#L264], after that {{root.dumpBatches()}} is called in {{FragmentExecutor.cleanup()}} method, so NPE will be thrown before releasing the resources and sending the final state.
