Looks like the datanucleus*.jar shouldn't appear in the hdfs path in Yarn-client mode.

Maybe this patch broke yarn-client.

Actually my HADOOP_CLASSPATH has already been set to include /etc/hadoop/conf/*

export HADOOP_CLASSPATH=/etc/hbase/conf/hbase-site.xml:/usr/lib/hbase/lib/hbase-protocol.jar:$(hbase classpath)

Looks like somehow Spark failed to find the core-site.xml in /et/hadoop/conf

I've already set the following env variables:

export YARN_CONF_DIR=/etc/hadoop/conf
export HADOOP_CONF_DIR=/etc/hadoop/conf
export HBASE_CONF_DIR=/etc/hbase/conf

Should I put $HADOOP_CONF_DIR/* to HADOOP_CLASSPATH?

I'm using latest Spark built from master HEAD yesterday. Is this a bug?
