Answer / Prabhat Mishra
File permissions in HDFS are similar to traditional Unix file permissions. They determine who can read, write or execute a file or directory. HDFS checks permissions using the PoSIX permission model. The user, group, and other have read, write, and execute permissions for files and directories.
