Hi,

I am trying to configure hadoop pseudo node secure cluster (to ensure
proper working) in Azure using Azure Domain Service.

OS - Windows Server 2012 R2 Datacenter
Hadoop Version - 2.7.2

I can able to run
*hadoop fs -ls /*

Example MapReduce job works fine
*yarn jar
%HADOOP_HOME%\share\hadoop\mapreduce\hadoop-mapreduce-examples-*.jar pi 16
10000*

But when i run,
*hdfs fsck /*

it gives,





















*Connecting to namenode via https://node1:50470/fsck?ugi=Kumar&path=%2F
