---------------------------------
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"
