Alan Gates commented on PIG-1420:
---------------------------------
Hudson is in the hospital rather than on vacation. Several of the machines
have crashed and we haven't managed to resuscitate them yet. We've been
running tests manually here. There's a test-patch target in ant that will run
the doc, release audit, etc. checks. Then a run of ant test (takes about 5
hours :( ) to confirm all the tests pass.
> Make CONCAT act on all fields of a tuple, instead of just the first two
> fields of a tuple

> Key: PIG-1420

> Project: Pig
> Issue Type: Improvement
> Components: impl
> Affects Versions: 0.8.0

> Fix For: 0.7.0

> Attachments: addconcat2.patch

> Original Estimate: 24h

> org.apache.pig.builtin.CONCAT (which acts on DataByteArray's internally) and
> org.apache.pig.builtin.StringConcat (which acts on Strings internally), both
> act on the first two fields of a tuple. This results in ugly nested CONCAT
> calls like:
> CONCAT(CONCAT(A, ' '), B)
> The more desirable form is:
> CONCAT(A, ' ', B)
> This change will be backwards compatible, provided that no one was relying on
> the fact that CONCAT ignores fields after the first two in a tuple. This
> seems a reasonable assumption to make, or at least a small break in
> compatibility for a sizable improvement.
