Subject [jira] Updated: (HBASE-1790) filters are not working correctly
Date Wed, 02 Sep 2009 02:18:33 GMT

     [ https://issues.apache.org/jira/browse/HBASE-1790?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jonathan Gray updated HBASE-1790:
---------------------------------

    Attachment: HBASE-1790-v4.patch

Adds new tests.  Adds new filters.  Makes a few changes to HRegion code and how filters are
run.  Modifies some existing tests to match updated semantics.  Add "early-out" to a few existing
filters so that we don't require an additional round-trip when we know we are done.

Also includes a modified version of Andrew's patch from HBASE-1807.

More work to be done, not ready for review...  Just checkpointing.

> Filters used in Scanning the table are not working correctly. For example a table with
three rows:
> 1. rowkey = adminbackslash-nb0, desc:temp = "temp"
> 2. rowkey = adminbackslash-nb1, desc:temp = "temp"
> 3. rowkey = adminkleptoman, desc:temp = "temp"
> If I scan all rows in the table without filter I get all the rows as expected. But applying
a simple prefixfilter with parameter "adminbackslash" will return only first row. I searched
it down to HRegion::nextInternal method, which will not output one passed row before denied
row(by filter).
