CassandraStorage does not function properly when used multiple times in a
single pig script due to UDFContext sharing issues
----------------------------------------------------------------------------------------------------------------------------
Key: CASSANDRA-2869
URL: https://issues.apache.org/jira/browse/CASSANDRA-2869
Project: Cassandra
Issue Type: Bug
Components: Contrib
Reporter: Grant Ingersoll
CassandraStorage appears to have threading issues along the lines of those
described at http://pig.markmail.org/message/oz7oz2x2dwp66eoz due to the
sharing of the UDFContext.
I believe the fix lies in implementing
{code}
public void setStoreFuncUDFContextSignature(String signature)
{
}
{code}
and then using that signature when getting the UDFContext.
>From the Pig manual:
{quote}
setStoreFunc!UDFContextSignature(): This method will be called by Pig both in
the front end and back end to pass a unique signature to the Storer. The
signature can be used to store into the UDFContext any information which the
Storer needs to store between various method invocations in the front end and
back end. The default implementation in StoreFunc has an empty body. This
method will be called before other methods.
