Commit Message

[ADAM-1680] Eliminate non-determinism in the ShuffleRegionJoin.

Resolves #1680. In the existing shuffle region join code, the partition
start/stop boundaries are determined by sorting the data and looking at the
coordinates of the first and last record on each partition. This is done via a
sampling process, which is fundamentally non-deterministic. Once these partition
bounds are picked, we replicate records from the right side of the join into the
partitions they overlap. There was a bug in this step that led to records being
dropped from the first partition of each contig (except for the first contig).
This was due to a bug in how the IntervalArray was being used to search for
repartitioning bounds.

This PR replaces the interval array with a map between contig names and the
partitions that contain their data. The first and last partition of each contig
are extended to the start/end of each contig.
