And again, got an invalid reply to another thread:
We're sorry, but your email message to ["discuss+ea2de3fbd163a266c975d1d2828884e4@elastic.co"]
(titled Re: [Hadoop and Elasticsearch] Is there a guide from creating uber jar with spark core and
elasticsearch-spark?) didn't work.
It looks at this point, at least for me, replying by email simply does not work...
Update: I sent two emails; the first one got the reply above, the next one made it as it can be seen in the thread here. This looks like a classical race condition when allocating keys...
