Eran Kutner commented on HBASE-4612:
------------------------------------
OK, I uploaded a patch for trunk, hopefully what I've done with the
createFilterFromArguments method makes sense.
> Allow ColumnPrefixFilter to support multiple prefixes

> Project: HBase
> Issue Type: Improvement
> Components: filters
> Affects Versions: 0.90.4
> Reporter: Eran Kutner

> Priority: Minor

> When having a lot of columns grouped by name I've found that it would be very
> useful to be able to scan them using multiple prefixes, allowing to fetch
> specific groups in one scan, without fetching the entire row. This is
> impossible to achieve using a FilterList, so I've added such support to the
> existing ColmnPrefixFilter while keeping backward compatibility.
> The attached patch is based on 0.90.4, I noticed that the 0.92 branch has a
> new method to support instantiating filters using Thrift. I'm not sure how
> the serialization works there so I didn't implement that, but the rest of my
> code should work in 0.92 as well.
