I have configured net.topology.node.switch.mapping.impl property in core-site.xml.The value of class is com.learning.rackawareness.RackAwareness. I already packaged the class to be jar and put it up Linux in hadoop path of /opt/modules/hadoop-2.7.2/share/hadoop/common/lib.
Then I used start-dfs.sh, Namenode failed.
where should I do to put the jar?
