----------------------------------------

Thank you [~suma.shivaprasad] for discussion.

# We might have to fix LogAggregationHtmlBlock#checkAcls too.

About solution for the problem, I was reading though S3 documentation. Can we 
make use of IAM folder and permission control.

# Configure separate bucket for logaggregation.(remote log directory) 
# Following IAM configuration for nodemanager and JHS(Deletion service runs in 
JHS)

For individual users folder access control using.

Will this work ??
