Hi, I want to make sure whether pig is integrated with Hbase. I mean, does pig support some query and other operations like create\write\append to HBase tables.
I found PIG6(http://issues.apache.org/jira/browse/PIG-6) tried to solve similar problems, but I don't know when this new feature and more similar features will be released in new version of pig.

Best Wishes!

Pig supports reading from Hbase (in Hadoop/Hbase 0.18 only).  It does  
not yet support writing to hbase.  We are open to accepting patches to  
add that functionality.  However, currently Pig's StoreFunc interface  
isn't good at working with non file based data.  We plan to make  
changes to that interface soon to better support storage functions  
writing to things like hbase.

Hello,

Do you have any link to the documentation about how to do that?
I can't find any example...

Thanks,

Using HBaseStorage as your loadFunc, it uses a customer slicer HBaseSlice

You can refer this link for more information

http://hadoop.apache.org/pig/docs/r0.3.0/udf.html#Custom+Slicer

Thank you for the link.

Anyway, what I was looking for is an example of PIG syntax loading
from a HBase table, is it something like:

queries = LOAD 'HBase Table" USING HBaseStorage()

?

See the JIRA PIG-6.  See also the HbaseStorage unit test that tests  
the functionality.
