[jira] [Comment Edited] (PIG-3558) ORC support for Pig
[ https://issues.apache.org/jira/browse/PIG-3558?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13904574#comment-13904574 ]

-----------------------------------------------------------------
I am pro adding ORC support in Pig, but against introducing massive dependencies.
According to http://mvnrepository.com/artifact/org.apache.hive/hive-exec/0.12.0 the hive-exec jar for 0.12 is 9 megs, and hides within it specific versions of jackson, snappy, org.json, chunks of thrift, hadoop.io (?!), avro, commons, protobuf, and guava. If ORC authors are not interested in improving their dependency hygene, they have to live with the fact that their project is unlikely to get integrated into other projects.
This is self-inflicted jar hell. Please don't do this. When ORC cleans up their dependencies, let's revisit.
