Subject [jira] [Commented] (HBASE-18361) CellComparator compare function should compare cell's value along with other attributes
Date Tue, 11 Jul 2017 15:27:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18361?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16082382#comment-16082382
] 

Amit Kabra commented on HBASE-18361:
------------------------------------

[~anoop.hbase] - Okay, didn't know that.

Cell interface has following attributes
 * 1) row
 * 2) column family
 * 3) column qualifier
 * 4) timestamp
 * 5) type
 * 6) MVCC version
 * 7) value
If two cell has different value why is it considered as same ?

> CellComparator.compare(Cell a, Cell b) should compare a and b's value as well.
> If we create two cells as 
>     byte [] row = Bytes.toBytes("row");
>     byte [] value = Bytes.toBytes("value");
>     byte [] value1 = Bytes.toBytes("value1");
>     Cell c1 = CellUtil.createCell(row, value);
>     Cell c2 = CellUtil.createCell(row, value1);
> And compare them using CellComparator.compare(c1, c2,true) , it returns 0 i.e it matches
them while they are different.CellComparator compares each attribute of cell but value.
