Issue while using Hive View in Ambari console

I am facing below issue while using Hive view from Ambari console:

E090 HDFS020 Could not write file /user/admin/hive/jobs/hive-job-3-2016-02-12_12-55/query.hql [HdfsApiException]

Searching through the guides I found out that HDFS user directory set up needs to be done. Following that guide am issuing command hadoop fs -mkdir /user/admin from HDFS user but it throws the below error.

-bash-4.1$ hadoop fs -mkdir /user/admin mkdir: `/user/admin': Input/output error

Need your help on this issue.

Note : Using HDP 2.3.4.0 and it was configured using Amabri and also in that host HDFS client is running.

Validate HDFS configuration and make sure HDFS service is running.

Input/Output error can be thrown because of multiple reasons (wrong config, NN not available,....)

Could you please check the HDFS Namenode Log and see if any error/exception is shown.

Thanks. hadoop.proxyuser.root.hosts=* also worked for me, too.

yes for some reason after enabling ranger , it will remoce the hadoop.proxyusers.root.hosts settings even if you had it before.... annoying
