Hi all,
1- I couldn't get TestHBaseStorage unit test running with hadoop-1.2.1 and
hbase-0.94.12. Is it supposed to work with those versions? The test hangs for
some time and fails with the exception below.
2- Is there any Pig function for deleting rows from an existing HBase
table? With some research I couldn't find one and I am implementing a store
function for that purpose. If anyone is interested I will be happy to
contribute it. The delete functionality can also be imitated with the existing
HBaseStorage function by storing the filtered tuples to a new HBase table, but
this has quite some overhead for large datasets.
Thanks,
Nezih
