Base hdfs file system permissions i am unable to understand..

[#1]

i have hdp sandbox 2.3..i login with user "sankar" and my hive warehouse directory having below file permission

hadoop fs -ls /apps/hive

drwxr-xr-x hive hdfs /apps/hive/warehouse

Here i see that owner having: rwx; group:r-x other: r-x permission

But while i login to sankar user i can easily put some data into that directory

i have attached below screen short

@sankar rao

Can you please check the value of dfs.permissions.enabled in your hdfs-site.xml? If this is false, permissions are not enforced.
