Hi Harsh,
I have a question of your description. The deleted tag masks the new
inserted value with old timestamp, that's why the new inserted data
can'be seen. But after major compaction, this new value will be seen
again. So, the question is that how the deletion really executes. In

Yonghu,
You are correct at that. Until a major_compact finishes, inserting
with old timestamps will never show. Inserted old timestamped values
before a major compact but after a delete will all go away.
That is why I had to put in the data into the table _after_ the
major_compact ran, in that
Indeed. Wrote simple unit-test [1] and it fails.
And there's a JIRA for that also:
https://issues.apache.org/jira/browse/HBASE-4364. I added patch with the
simple unit-test that fails to it.

Yeah... It looks OK.
Maybe 2G of heap is a bit low when dealing with 200.000 column rows.
If you can I'd like to know how busy your regionservers are during these
operations. That would be an indication on whether the parallelization is good
or not.

Hi
Just to add on, The HLog is just an edit log. Any transaction updates(
Puts/Deletes) are just added to HLog. It is the Scanner that takes care of
the TTL part which is calculated from the TTL configured at the column
family(Store) level.

Ram
