Re: MapReduce reindexing with authentication

Hi Boxuan,

Yes, I did not finish my argument. What I tried to suggest: if the hadoop CLI command checks the GENERIC_OPTIONS env variable, then maybe also the mapreduce java client called by JanusGraph checks the GENERIC_OPTIONS env variable.

The (old) blog below suggests, however, that this behavior is not present by default but requires the janusgraph code to run hadoop's ToolRunner. So, just see if this is any better than what you had in mind to implement.
