> Filters are not properly applied in certain cases
> -------------------------------------------------
>
> Key: HBASE-6912
> URL: https://issues.apache.org/jira/browse/HBASE-6912
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.94.1
> Reporter: Alex Newman
> Fix For: 0.94.2, 0.96.0
>
> Attachments: 6912-0.94.txt, 6912-0.96.txt, minimalTest.java
>
>
> Steps to reproduce:
> Create a table, load data into it. Flush the table.
> Do a scan with
> 1. Some filter which should not match the first entry in the scan
> 2. Where one specifies a family and column.
> You will notice that the first entry is returned even though it doesn't match
> the filter.
> It looks like the when the first KeyValue of a scan in the column from the
> point of view of the code
> HRegion.java
> {code}
> } else if (kv != null && !kv.isInternal() && filterRowKey(currentRow)) {
> {code}
> Is generated by
> {code}
> public static KeyValue createLastOnRow(final byte [] row,
> final int roffset, final int rlength, final byte [] family,
> final int foffset, final int flength, final byte [] qualifier,
> final int qoffset, final int qlength) { return new KeyValue(row, roffset,
> rlength, family, foffset, flength, qualifier, qoffset, qlength,
> HConstants.OLDEST_TIMESTAMP, Type.Minimum, null, 0, 0); }
> {code}
> So it is always internal from that point of the code.
> Only later from within
> StoreScanner.java
> {code}
> public synchronized boolean next(List<KeyValue> outResult, int limit, String
> metric) throws IOException {
> ....
> LOOP: while((kv = this.heap.peek()) != null) {
> {code}
> ( The second time through)
> Do we get the actual kv, with a proper type and timestamp. This seems to mess
> with filtering.
