Vishal Khandelwal resolved HBASE-18460.
---------------------------------------
Resolution: Not A Problem
> Rows are not getting deleted once TTL crosses and minversion is 0
> -----------------------------------------------------------------
>
> Key: HBASE-18460
> URL: https://issues.apache.org/jira/browse/HBASE-18460
> Project: HBase
> Issue Type: Bug
> Affects Versions: 1.3.0
> Reporter: Vishal Khandelwal
> Attachments: test.patch, TestTTL.java
>
>
> Wrote a Simple program to find the different behavior between 0.98 Vs
> hbase.1.3
>
> Here is the scenario :
>
> 1. Create a table with minversion=1, TTL = 60 secs
> 2. Create a row 'r1' with ts = currentTime
> 3. Create a row 'r2' with ts = currentTime - 2 *tll
> 4. flush and majorcompact
>
> Expected behavior from is if we do with raw=true or raw=false. number of rows
> should be = 1. scanner should only print values beyond ttl, This behavior is
> different for 0.98 and 1.3
>
> In 0.98
> 1) keyvalues={a/family:family/1501052690599/Put/vlen=6/mvcc=0}
> Final countWithRaw = 1
> 1) keyvalues={a/family:family/1501052690599/Put/vlen=6/mvcc=0}
> Final countWithoutRaw = 1
>
> whereas for same code in 1.3 it is giving following ouput
> 2) keyvalues={a/family:family/1501052754670/Put/vlen=6/seqid=0,
> a/family:family/1500932754662/Put/vlen=1/seqid=0}
> Final countWithRaw = 2
> 1) keyvalues={a/family:family/1501052754670/Put/vlen=6/seqid=0}
> Final countWithoutRaw = 1
>
> So even after if I trigger admin.majorCompact for the table. number of rows
> with rawScan=true shows 2 rows where "isDelete" property is also false. This
> does note seem to correct behavior with hbase1.3 where rows are not getting
> deleted after it crosses TTL/major compaction and Scanner can still fetch
> them with raw=true.
> Here is the output from the test i have written
> < ==== hbase.1.3 ===>
> countBeforeFlushWithRaw = 3
> countBeforeFlushWithoutRaw = 1
> countAfterFlushWithRaw = 3
> countAfterFlushWithoutRaw = 1
> countAfterCompactionWithRaw = 3
> countAfterCompactionWithoutRaw = 1
> < ====== hbase 0.98.24 >
> countBeforeFlushWithRaw = 1
> countBeforeFlushWithoutRaw = 1
> countAfterFlushWithRaw = 1
> countAfterFlushWithoutRaw = 1
> countAfterCompactionWithRaw = 1
> countAfterCompactionWithoutRaw = 1
