> Currently, the CacheAdmin usage shows the "maxttl" option for -addPool, but the option should be listed as "maxTtl" instead.
> If users attempt to use "maxttl" they will see the following error:
> {code}
> bash-4.1$ hdfs cacheadmin -addPool pool2 -maxttl 10s
> Can't understand arguments: -maxttl 10s
> Usage is [-addPool <name> [-owner <owner>] [-group <group>] [-mode <mode>] [-limit <limit>] [-maxttl <maxTtl>]
> {code}
> We should change the usage to usage "maxTtl"
