What happens when two users try to access to the same file in HDFS?..

Answer / Navneet Kumar Verma

In HDFS, only one user can write to a file at any given time. If two users attempt to write to the same file simultaneously, the second user will receive an error. However, multiple users can read from the same file concurrently without any issues.
