Review request for hbase and Todd Lipcon.
Changes
-------
Cleaned up nit.
Summary
-------
When HFiles are flushed through the normal path, they include an attribute
TIMERANGE_KEY which can be used to cull HFiles when performing a
time-restricted scan. Files produced by HFileOutputFormat are currently missing
this metadata.
This addresses bug HBASE-4148.

Testing
-------
Added unit test.
I don't quite understand why the KeyValue with the larger timestamp (2000)
value must be written before the one with the smaller timestamp (1000). I can
see the code that enforces this (HFile.checkKey) but not why keys are larger to
smaller. Is this in HFile data precondition?
I cannot get the full test suite to pass, with or without this patch. Suite
seems to timeout on tests unrelated to this. Would appreciate some hints or
pointers for info on which tests are flakey or take a long time to run.
Thanks,
jmhsieh
