Pig storage handler should implement LoadMetadata
-------------------------------------------------
Key: CASSANDRA-2777
URL: https://issues.apache.org/jira/browse/CASSANDRA-2777
Project: Cassandra
Issue Type: Improvement
Components: Contrib
Reporter: Brandon Williams
Assignee: Brandon Williams
Priority: Minor
The reason for this is many builtin functions like SUM won't work on longs (you
can workaround using LongSum, but that's lame) because the query planner
doesn't know about the types beforehand, even though we are casting to native
longs.
There is some impact to this, though. With LoadMetadata implemented, existing
scripts that specify schema will need to remove it (since LM is doing it for
them) and they will need to conform to LM's terminology (key, columns, name,
value) within the script. This is trivial to change, however, and the
increased functionality is worth the switch.
