Eli Collins commented on HDFS-3489:
-----------------------------------
Per HDFS-3483 it should require a file system with scheme hdfs.
> hdfs fsck usage message is outdated
> -----------------------------------
>
> Key: HDFS-3489
> URL: https://issues.apache.org/jira/browse/HDFS-3489
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 2.0.0-alpha
> Reporter: Andy Isaacson
> Assignee: Andy Isaacson
> Priority: Minor
>
> The help message from "hdfs fsck" is misleading in several ways.
> {code}
> Usage: DFSck <path> [-list-corruptfileblocks | [-move | -delete |
> -openforwrite] [-files [-blocks [-locations | -racks]]]]
> <path> start checking from this path
> -move move corrupted files to /lost+found
> -delete delete corrupted files
> -files print out files being checked
> -openforwrite print out files opened for write
> -list-corruptfileblocks print out list of missing blocks and files
> they belong to
> -blocks print out block report
> -locations print out locations for every block
> -racks print out network topology for data-node locations
> By default fsck ignores files opened for write, use
> -openforwrite to report such files. They are usually tagged CORRUPT or
> HEALTHY depending on their block allocation status
> Generic options supported are
> -conf <configuration file> specify an application configuration file
> -D <property=value> use value for given property
> -fs <local|namenode:port> specify a namenode
> -jt <local|jobtracker:port> specify a job tracker
> -files <comma separated list of files> specify comma separated files to be
> copied to the map reduce cluster
> -libjars <comma separated list of jars> specify comma separated jar files
> to include in the classpath.
> -archives <comma separated list of archives> specify comma separated
> archives to be unarchived on the compute machines.
> The general command line syntax is
> bin/hadoop command [genericOptions] [commandOptions]
> {code}
> - the first line should not say "DFSck"
> - the -fs option prefers a hdfs:// URI rather than a bare namenode:port pair
