Hadoop cannot access /logs/. in secure mode

问题:

I am using hadoop-2.6.0 and enabled security with kerberos. All working fine. But i am unable to access the logs files from browser. It shows

Problem accessing /logs/. Reason:

User babu is unauthorized to access this page.

I tried with all users but no luck.

Can anyone help me how to authorize any user to access log files?

You shouldn't access the logs directly in the FS, access is restricted to the NM user and the yarn group. Use the log-aggregation service to retrieve/view logs. See Simplifying user-logs management and access in YARN.
