I have been working on balancing work across a number of partitions and find it would be useful to access information about the current execution environment much of which (like Executor ID) are available if there was a way to get the current executor or the Hadoop TaskAttempt context - does any one on the list know how to access this object from a function running on a slave. Currently I am reduced to tracking Mac Address to at least know which machine code is running on but there must be a better way
