[jira] [Created] (HDFS-17475) Add a command to check if files are readable

Felix N created HDFS-17475:
------------------------------

             Summary: Add a command to check if files are readable
                 Key: HDFS-17475
                 URL: https://issues.apache.org/jira/browse/HDFS-17475
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: hdfs
            Reporter: Felix N
            Assignee: Felix N
             Fix For: 3.5.0


Sometimes a job can fail due to one unreadable file down the line due to missing replicas or dead DNs or other reason. This command should allow users to check whether files are readable by checking for metadata on DNs without executing full read pipelines of the files.
