mokai commented on HBASE-21622:
-------------------------------

Is it any progress? Shall us fix it?

I tested it on my env with hbase 2.2.3, the results are different if hfile compacted before/after cell expired.

*Precondition:* set VERSIONS to 1.

*Scenario 1：*
 # put 'test_table', 'row1', 'f1:c1','a';
 # put 'test_table', 'row1', f1:c1','b', set cell TTL to 60s;
 # waiting cell expired;
 # get'test_table', 'row1', got value 'a';

*Scenario 2:*
 # put 'test_table', 'row1', 'f1:c1','a';
 # put 'test_table', 'row1', f1:c1','b', set cell TTL to 60s;
 # major_compact 'test_table';
 # waiting cell expired;
 # get 'test_table', 'row1', got none value;

The old versions were deleted while compacting.
