> Duplicate generic usage information to hdfs debug command
> ---------------------------------------------------------
>
> Key: HDFS-16282
> URL: https://issues.apache.org/jira/browse/HDFS-16282
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: tools
> Affects Versions: 3.3.0, 3.3.1
> Reporter: daimin
> Assignee: daimin
> Priority: Minor
> Labels: pull-request-available
> Time Spent: 1h

> When we type 'hdfs debug' in console, the generic usage information will be
> repeated 4 times and the target command like 'verifyMeta' or 'recoverLease'
> seems hard to find.
> {quote}~ $ hdfs debug
> Usage: hdfs debug <command> [arguments]
> These commands are for advanced users only.
> Incorrect usages may result in data loss. Use at your own risk.
> verifyMeta -meta <metadata-file> [-block <block-file>]
> Generic options supported are:
> -conf <configuration file> specify an application configuration file
> -D <property=value> define a value for a given property
> -fs <file:///|hdfs://namenode:port> specify default filesystem URL to use,
> overrides 'fs.defaultFS' property from configurations.
> -jt <local|resourcemanager:port> specify a ResourceManager
> -files <file1,...> specify a comma-separated list of files to be copied to
> the map reduce cluster
> -libjars <jar1,...> specify a comma-separated list of jar files to be
> included in the classpath
> -archives <archive1,...> specify a comma-separated list of archives to be
> unarchived on the compute machines
> The general command line syntax is:
> command [genericOptions] [commandOptions]
> computeMeta -block <block-file> -out <output-metadata-file>
