Implemented the patch from CASSANDRA-11988, the noticeable change is when
gc_grace_seconds is set to a year, a select * will now show the data +
tombstone'd partitions.
With gc_grace_seconds set to 1 day, still getting the
java.lang.NullPointerException error.

FYI, we're having the same issue (CASSANDRA-12215).
I implemented the patch, set gc_grace_seconds to 86400, and still ran into the
error. Setting the gc_grace_seconds to something high, all rows show up,
including the ones that are supposed to be tombstones.

One thing I noticed, when setting the gc_grace_seconds to 864 (100 days),
the tables are readable and compaction runs without error.
Enabling tracing, doing a select * from the table shows 4 tombstones:
{code}
Read 124 live and 4 tombstone cells [SharedPool-Worker-2] | 2016-07-20
14:09:17.236000 | 127.0.0.1 | 1849
{code}
I have run
- COPY table TO 'file'
- DROP table
- rm -rf'd the table directory on the file system
- CREATE table (with same schema)
- COPY table FROM 'file'
- Ran the select * again, and the tombstones still exist.
Expected behavior would be a clean table with no tombstones, yet the 4
tombstones exist. Reviewing the 'dump' file shows no tombstones.

I have run a COPY TO, truncated the table, then ran a COPY FROM, ran the select
* again, and the tombstones still exist.
Reviewing the 'dump' file, I'm not seeing anything marked tombstones and the
data looks fine. My understanding is, compaction should remove the tombstone
records if it's past the gc_grace_seconds limit. Also, if the 'dump' file
doesn't show tombstones, where is cassandra retrieving that info?

Since the table is pretty small, I can do a copy to, truncate the table, and
copy from, and the table is fine. But my concern is if compaction fails to
remove those rows, and the table will eventually be very large in a production
environment, the copy, truncate, and copy will no longer be an option.
