[jira] Created: (HBASE-2227) [IHBASE] Idx Expression functionality is incompatible with SingleColumnValueFilter

[IHBASE] Idx Expression functionality is incompatible with SingleColumnValueFilter  
------------------------------------------------------------------------------------

                 Key: HBASE-2227
                 URL: https://issues.apache.org/jira/browse/HBASE-2227
             Project: Hadoop HBase
          Issue Type: Bug
    Affects Versions: 0.20.4
            Reporter: Yoram Kulbak
             Fix For: 0.20.4


Idx comparison expressions should have 1:1 mapping to SingleColumnValueFilter.
Without this mapping users can't fully use the index expressions to optimize their scan performance.
Currently there are two main features lacking:
- Support for a != (NEQ) operator 
- Support for the 'filterIfMissing' modifier
