stack updated HADOOP-1579:
--------------------------
Status: In Progress (was: Patch Available)
Fail is in test of hbase bloom filters, something that I've not noticing
failing in the past. It looks like it was stuck for 15 minutes. Rebuilt
local. All again passes. Trying resubmit
> [hbase] Add new WhileMatchRowFilter and StopRowFilter filters

> I've created two additional filters for HBase: WhileMatchRowFilter and
> StopRowFilter. WhileMatchRowFilter is an extension of RegExpRowFilter; it
> also filters rows based on whether they match a specified regex. However,
> unlike its parent, WhileMatchRowFilter filters everything after it's first
> filtered row - once a row fails to match regex or column specifications,
> filterAllRemaining() always returns true. This type of functionality will be
> useful when filtering for a set of adjacent rows that match a certain regex
> (as opposed to every row that matches that regex).
> StopRowFilter filters out every row greater than or equal to a specified
> rowKey (the stopRow). The filter assumes that the rowKeys it receives are in
> alphabetical order, so once a key greater than the stopRow is encountered
> filterAllRemaining() will return true. StopRowFilter will be useful for
> alphabetical filtering.
> Both filters come with JUnit tests, namely TestWhileMatchRowFilter and
> TestStopRowFilter.
