I found out the issue, actually we enabled the spnego for atlas therefore it was checking the spnego.service.keytab file. Somehow user "atlas" got removed from the application group therefore didn't had read permission on spnego.service.keytab file. Once we given read permission issue got resolved. Thanks

Hi @Bala Vignesh N V The above approach is pretty good and work very well when you having small number of files but what if you have thousands or millions of files in directories? In that case its better to use Hadoop Mapreduce framework to do same job on large files but in less time. Below is an example to count lines using mapreduce. https://sites.google.com/site/hadoopandhive/home/hadoop-how-to-count-number-of-lines-in-a-file-using-map-reduce-framework

I would highly suggest you to upgrade your ambari server with latest release. As a workaround restart the Ambari (server and agents) as well as Ambari Metrics and see if that resolve the issue.
