Hi Uma !
I have added in hdfs-site.xml the following
<property>
<name>dfs.permissions</name>
<value>false</value>
</property>
and restarted the cluster.
I tried :
arun@arun-Presario-C500-RU914PA-ACJ:~$ /home/hduser/hadoop203/bin/hadoop jar
/home/hduser/hadoop203/hadoop-examples*.jar pi 1 1
Number of Maps = 1
Samples per Map = 1
org.apache.hadoop.ipc.RemoteException:
org.apache.hadoop.hdfs.server.namenode.SafeModeException: Cannot create
directory /user/arun/PiEstimator_TMP_3_141592654/in. Name node is in safe
mode.
The ratio of reported blocks 0.0000 has not reached the threshold 0.9990.
Safe mode will be turned off automatically.
