------------------------------
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.
