[jira] [Commented] (PIG-3444) CONCAT with 2+ input parameters fail

    [ https://issues.apache.org/jira/browse/PIG-3444?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13803475#comment-13803475 ] 

Daniel Dai commented on PIG-3444:
---------------------------------

Thanks Lorand, this is a long desired feature.

Wonder if we can put the flag in EvalFunc instead of Schema? Schema change will probably propagate to other part of Pig code, and seems nowhere else in Pig would need variable schema.

> This is a continuation work of PIG-1420 since PIG-1420 is closed. Currently CONCAT fails with more than 2 parameters. The error message is:
> Could not infer the matching function for org.apache.pig.builtin.CONCAT as multiple or none of them fit
