[jira] [Commented] (PIG-3222) New UDFContextSignature assignments
in Pig 0.11 breaks HCatalog.HCatStorer
[ https://issues.apache.org/jira/browse/PIG-3222?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13887216#comment-13887216 ]
Viraj Bhat commented on PIG-3222:
---------------------------------
Hi Feng,
Thanks for finding this error in Pig 0.11. It seems the limit to HCatStorer works fine with Pig 0.12 but is still a problem with Pig 0.11. Not sure if we need to backport something that got this working in Pig 0.12

> Pig 0.11 assigns different UDFContextSignature for different invocations of the same load/store statement. This change breaks the HCatStorer which assumes all front-end and back-end invocations of the same store statement has the same UDFContextSignature so that it can read the previously stored information correctly.
> The related HCatalog code is in https://svn.apache.org/repos/asf/incubator/hcatalog/branches/branch-0.5/hcatalog-pig-adapter/src/main/java/org/apache/hcatalog/pig/HCatStorer.java (the setStoreLocation() function).
