[jira] [Created] (HDFS-5701) Fix the CacheAdmin -addPool -maxTtl option name

Stephen Chu created HDFS-5701:
---------------------------------

             Summary: Fix the CacheAdmin -addPool -maxTtl option name
                 Key: HDFS-5701
                 URL: https://issues.apache.org/jira/browse/HDFS-5701
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: caching, tools
    Affects Versions: 3.0.0
            Reporter: Stephen Chu
            Priority: Minor
             Fix For: 3.0.0


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"
