[jira] [Commented] (PIG-5187) UdfDistributedCache_1 is failing with
spark exec type
[ https://issues.apache.org/jira/browse/PIG-5187?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15907866#comment-15907866 ]
Nandor Kollar commented on PIG-5187:
------------------------------------
When no files are shipped/cached, cacheFiles and shipFiles still wants to add a file with empty string as name. Added PIG-5187_1.patch to fix this problem.

> UdfDistributedCache_1 fails, because Java EvalFunc#getCacheFiles is not handled, thus files are not added to SparkContext:
