Description

in core-site.xml if default filesystem's uri is misconfigured , NN does not come up and in NN shows NPE

java.lang.NullPointerException
at org.apache.hadoop.net.NetUtils.createSocketAddr(NetUtils.java:142)
at org.apache.hadoop.hdfs.server.namenode.NameNode.getAddress(NameNode.java:195)

It is better to give meaningful error messege than NPE
