Russell Jurney commented on PIG-1420: ------------------------------------- Looks like a new FuncSpec type needs to be implemented? > Make CONCAT act on all fields of a tuple, instead of just the first two > fields of a tuple > ----------------------------------------------------------------------------------------- > > Key: PIG-1420 > URL: https://issues.apache.org/jira/browse/PIG-1420 > Project: Pig > Issue Type: Improvement > Components: impl > Affects Versions: 0.8.0 > Reporter: Russell Jurney > Assignee: Russell Jurney > Labels: five, high > Fix For: 0.8.0 > > Attachments: addconcat2.patch, PIG-1420.2.patch > > Original Estimate: 24h > Remaining 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. -- This message is automatically generated by JIRA.
