> ---------------------------------------------------
>
> Key: HDFS-5468
> URL: https://issues.apache.org/jira/browse/HDFS-5468
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: tools
> Affects Versions: 3.0.0, 2.3.0
> Reporter: Stephen Chu
> Assignee: Stephen Chu
> Priority: Minor
> Fix For: 2.3.0
>
> Attachments: HDFS-5468.patch
>
>
> Currently, the hdfs cacheadmin -help command will not recognize correct
> command inputs:
> {code}
> [hdfs@hdfs-cache ~]# hdfs cacheadmin -help listPools
> Sorry, I don't know the command 'listPools'.
> Valid command names are:
> -addDirective, -removeDirective, -removeDirectives, -listDirectives,
> -addPool, -modifyPool, -removePool, -listPools, -help
> [hdfs@hdfs-cache ~]# hdfs cacheadmin -help -listPools
> Sorry, I don't know the command 'listPools'.
> Valid command names are:
> -addDirective, -removeDirective, -removeDirectives, -listDirectives,
> -addPool, -modifyPool, -removePool, -listPools, -help
> {code}
> In the code, we strip the input command of leading hyphens, but then compare
> it to the command names, which are all prefixed by a hyphen.
> Also, cacheadmin -removeDirectives requires specifying a path with -path but
> -path is not shown in the usage. We should fix this as well.
