Data Node Not Starting

ccasano — Thu, 12 Nov 2015 11:17:17 GMT

The following error is generated when adding a new data node to the cluster:

WARN datanode.DataNode (DataNode.java:checkStorageLocations(2407)) - Invalid dfs.datanode.data.dir

Even if the path is right, check the permissions. Typically the hdfs user should be the owner the group should be hadoop for the data directory:

chown -R hdfs /path-to-your-datanode-data-dir

chgrp -R hadoop /path-to-your-datanode-data-dir

chmod 750 /path-to-your-datanode-data-dir
