Jonathan Hsieh updated HBASE-9262:
----------------------------------
Release Note: Previously, when using a WriterFactory to create an HFile
writer, the HFile Writer would default to using a raw byte array comparator
instead of one that was aware of the a KV's Key structure. All actual
instances of HFileWriter creation required the specification of a
KEY_COMPARATOR. With this modification the KEY_COMPARATOR becomes the default,
and we add a special comparator for unit tests that required the rare old
default semantics.
> Make KeyValue.KEY_COMPARATOR default for HFile WriterFactory

> This takes completed work mentioned in HBASE-9247 as a reasonably sized patch
> to build upon.
> * Fixed defaults in HFile.Writer factory to default to Key-format-aware
> comparator (KeyComparator, later converted to KVComparator) instead of a
> Key-format oblivious byte[] comparator. (Essentially all instances require
> specifying KEY_COMPARATOR – why not just make it the default).
> ** Found that TestSeekTo, TestReseekTo and a handful of others depend on a
> different comparator because – HBASE-7845 "breaks" assumptions in these tests.
> * Moved getComparator into TableName. (removed an instanceof bad smell)
