Subject [jira] [Commented] (SPARK-2075) Anonymous classes are missing from Spark distribution
Date Sat, 20 Dec 2014 13:08:13 GMT

    [ https://issues.apache.org/jira/browse/SPARK-2075?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14254720#comment-14254720

Sun Rui commented on SPARK-2075:
--------------------------------

[~srowen] I assume that mvn jars were built for Hadoop 1.x as you said that "A default mvn
release would use hadoop.version=1.0.4. Somebody can correct me if this isn't the case, but
I assume that this is what goes to Maven Central." :) so it is very possible that mvn jars
were actually built for Hadoop 2.x, which is the cause for this issue.

Yes, I agree that we should using match binaries. The problem is that we thought we are using
the matching binaries but actually not. So we need a way to avoid this (documentation, or
fixing )

> Running a job built against the Maven dep for 1.0.0 and the hadoop1 distribution produces:

> java.lang.ClassNotFoundException:

> {code}
> Here's what's in the Maven dep as of 1.0.0:

> I.e., it's not there.  It is in the hadoop2 distribution:
