fixed in version 1.26

Same problem for disable_vol.sh:
# ./disable_vol.sh --help | grep rhs_node
  --rhs_node   : (optional) hostname of any of the storage nodes. This is needed in

# rpm -q rhs-hadoop-install
  rhs-hadoop-install-1_32-1.el6rhs.noarch

>> ASSIGNED

fixed disable_vol.sh in version 1.33, but not sure if I am supposed to do a brew build of this latest version.

I found few other inconsistencies in help texts for scripts setup_cluster, {create,enable,disable}_vol.sh - I think it is still related to the context of this BZ and hopefully I didn't miss anything.
If it is already out of scope from this bug, fell free to return it back to MODIFIED and I'll create new BZ with following issues.

setup_cluster.sh:
  * --hadoop-management-node versus --hadoop-mgmt-node
  * <nodes-spec-list> versus <node-spec-list> 
  * Each node is expected to be separate from the management and yarn-master nodes.
    - (and similarly for --yarn-master and --hadoop-mgmt-node) - this is recommended, but scenarios with management or yarn-master inside the storage pool are also supported (if I'm right)
    - this apply also for all following scripts

create_vol.sh:
  * <volume-mnt-prefix> versus <vol-mnt-prefix>
  * <node-list-spec> versus <node-spec-list>

enable_vol.sh:
  * --hadoop-management-node versus --hadoop-mgmt-node

disable_vol.sh:
 * --hadoop-management-node versus --hadoop-mgmt-node

Thanks for being thorough in checking the usage verbage! I've fixed the above errors in version 2.01, which is potentially post-Denali. The 2.x version supports the HDP 2.1 stack and is opportunistic for the Denali release.

For rhs-hadoop-install-2_08-1.el6rhs.noarch following issues are still valid:

setup_cluster.sh --help:
  * <nodes-spec-list> versus <node-spec-list> (there are mentioned both versions, in other scripts is used node-spec-list)

  * Each node is expected to be separate from the management and yarn-master nodes.
    - this was changed only for setup_cluster.sh - <node-spec>, but --yarn-master and --hadoop-mgmt-node in each script, it is still described like:
    --yarn-master   : (optional) hostname or ip of the yarn-master server which is
                    *expected to be outside of the storage pool*. Default is localhost.

Please also check following sentence (./setup_cluster.sh --help), the conmbination of "is" and "be" sounds strange for me, but English is not my strong suit...

  It is recommended that each node is be separate from the mgmt and yarn-master nodes.

Daniel, your English is fine and you are correct about the typo/grammatical error in setup_cluster's usage(). I've once again attempted to make the nodes-spec-list consistent across setup_cluster and create_vol. Fixed in 2.09/
