Announce: MR3 0.7 released

I am pleased to announce the release of MR3 0.7. New key features are:

- MR3 is fully fault-tolerant. (

- The logic for node blacklisting has been simplified. (

I have tested the correctness of Hive on MR3 by cross-checking the result
of TPC-DS benchmark against Impala and Presto. Nothing particularly
surprising, except that for some queries, Impala returns different results
than Hive on MR3 and Presto. Hive on MR3 is consistent with Presto for
TPC-DS benchmark.

I have created an FAQ page:
