      Description

      Currently, the hdfs cacheadmin -help command will not recognize correct command inputs:

      [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
      

      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.
