e572e59673f6dade62f96eb38b6417ef018bc7bf [catalog_manager] KUDU-2671 fix bug in CreatePartitionsForRange()
This patch fixes a bug in PartitionSchema::CreatePartitionsForRange().
The manifestation of the bug was the inability to add an unbounded range
with custom hash schema (e.g. [0, +inf)) by AlterTable due to a conflict
with already existing range (e.g., [-inf, 0)) when if fact there was no
conflict at all. The root cause was the assumption that PartitionSchema
contained information on the range to be added in its internal map
'hash_schema_idx_by_encoded_range_start_' but that wasn't the case,
so GetHashSchemaForRange() would return the table-wide hash schema for
the new range being added instead of proper range-specific hash schema.
That lead to incorrect updating of range boundaries in
UpdatePartitionBoundaries(), producing wrong results.
This patch also contains a new test scenario that allowed to reproduce
the issue: the new scenario is failing without the fix applied.
