FilterList with MUST_PASS_ONE and SCVF isn't working
----------------------------------------------------
Key: HBASE-3191
URL: https://issues.apache.org/jira/browse/HBASE-3191
Project: HBase
Issue Type: Bug
Components: filters
Affects Versions: 0.89.20100924, 0.90.0
Reporter: Stefan Seelmann
Priority: Minor
In a special case the FilterList with MUST_PASS_ONE operator doesn't work
correctly:
- a filter in the list is a SingleColumValueFilter with filterIfMissing=true
- FilterList.filterKeyValue(KeyValue) is called
- SingleColumValueFilter.filterKeyValue(KeyValue) is called
- SingleColumValueFilter.filterKeyValue(KeyValue) returns ReturnCode.INCLUDE if
the KeyValue doesn't match a column (to support filterIfMissing)
- FilterList.filterKeyValue(KeyValue) immediately returns ReturnCode.INCLUDE,
remaining filters in the list aren't evaluated.
However it is required to evaluate remaining filters, otherwise filterRow()
filters out rows in case the filter's filterKeyValue() saves state that is used
by filterRow(). (SingleColumValueFilter, SkipFilter, WhileMatchFilter do so)
