Hi Muhammad,

From what I've googled= a few months ago on the subject, MatchPath UDF has been removed from Cloud= era and Hortonworks releases because TeraData=C2=A0
claims it vio= lates one of their patent (apparently renaming it did not suffice).

I guess that if you really need it, it might be possibl= e to add it yourself as an external UDF since the code is still available o= ut there, but I have no idea
whether TeraData would have the righ= t to come after you (or not?) if you do.

By the way, if anyone has news on the current situation= with MatchPath and TerraData, that would be welcome.

Hi,

Many thanks for sending these links. = Looking forward to more documentation around this.

BTW, why do= es " hive-exec= -0.13.0.2.1.1.0-385.jar" not have any class files for MatchPath= UDF ? Have they been chucked out to a separate JAR file?
I can see tha= t " hive-exec= -0.13.0.jar" has the appropriate class files, and have tried to= use them. They work well with the demo data set but we certainly need more= documentation around this.

Regards,
Asif Abbasi
