Subject [jira] [Commented] (HAMA-848) Refactor YARN module for hadoop 2.x stable version
Date Mon, 02 Mar 2015 14:31:05 GMT

    [ https://issues.apache.org/jira/browse/HAMA-848?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14343188#comment-14343188
] 

Minho Kim commented on HAMA-848:
--------------------------------

An error happened when I was testing it on amazon EMR cluster.
{code}
SLF4J: Class path contains multiple SLF4J bindings.
{code}
I think that the problem is caused by same binding of SLF4J lib in Hadoop and Hama.

Are there any ideas to solve the problem?

> Current yarn-module was implemented based on Hadoop 0.23.1 version. You'll need to use
the Hama RPC instead of Hadoop RPC.
