Lars George updated HBASE-1990:
-------------------------------
Attachment: TestHTableGenerics.java
TestHTableGenerics.java is a sample of how we could add generics support to the
classes. Now, this could be in a contrib package, but maybe even in the
standard API. Biggest issue is of course the API change again. And we want to
keep the API as simple as possible I would assume and with byte[] it is already
as generic as possible.
I would opt for those classes to be in contrib, fully implemented of course and
properly layed out and tested. My classes above are just an attempt to show a
general idea, which is how to make a wrapper framework that adds all the
various type support.
What do you all think?
> Add methods accepting strings for family/qualifier in client
> -------------------------------------------------------------
>
> Key: HBASE-1990
> URL: https://issues.apache.org/jira/browse/HBASE-1990
> Project: Hadoop HBase
> Issue Type: Improvement
> Components: client
> Affects Versions: 0.20.0
> Reporter: Doug Meil
> Priority: Minor
> Fix For: 0.21.0, 0.20.3
>
> Attachments: TestHTableGenerics.java
>
>
> Consider the following client code...
> byte b[] = result.getValue( Bytes.toBytes("family"),
> Bytes.toBytes("qualifier") );
> put.add( Bytes.toBytes("family"), Bytes.toBytes("qualifer"),
> Bytes.toBytes( "value") );
> ... the requirement to supply family and qualifiers as bytes causes code to
> get cluttered and verbose. At worst, it scares peoples un-necessarily about
> HBase development, and at best, developers inevitably will get tired of doing
> all this casting and then add their own wrapper classes around the HBase
> client to make their code more readable.
> I would like to see something like this in the API...
> byte b[] = result.getValue( "family"), "qualifier" );
> put.add( "family", "qualifer", Bytes.toBytes( "value") );
> ... where the Hbase client can perform the required Bytes.toBytes()
> conversion behind the scenes.
