Subject [jira] [Commented] (ACCUMULO-1421) use reflection to improve compatibility between Hadoop 1 and 2 JobContext objects
Date Thu, 16 May 2013 16:47:16 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-1421?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13659694#comment-13659694
] 

Sean Busbey commented on ACCUMULO-1421:
---------------------------------------

The version is very relevant. I need to test on the opposite one to make sure we haven't missed
references to incompatible classes.

I guess I can just search through the byte code. :/

> JobContext switches between an abstract class and an interface in hadoop 1 and 2, causing
runtime compatibility problems in the compiled Accumulo bytecode. Avoid the runtime problem
by using reflection to access the configuration object stored in the JobContext.
