Alan Gates commented on PIG-2889:
---------------------------------
Hive has an AvroSerDe which I believe can read schema on the fly like this.
This should just work with HCat. In theory this should work with HBase as
well, since SerDes are independent of IF/OF and storage handlers in Hive/HCat.
This would all need to be tested.
All that said, there's nothing to prevent you from doing it as you propose in
Pig without HCat.

> I want to use HBaseStorage without specifying the schema. Storing data in
> Avro format in HBase is a very common practice. I would like to create a UDF,
> HBaseAvroStorage that works just like the internal HBaseStorage UDF, but
> loads the Avro schema metadata so that specifying a schema is unnecessary.
> I haven't thought through all the particulars, so if you have - please chime
> in :)
> I am also not sure if this isn't sort of handled some place in HCatalog?
