--------------------------------
Summary: CacheAdmin command usage message not shows completely
Key: HDFS-10404
URL: https://issues.apache.org/jira/browse/HDFS-10404
Project: Hadoop HDFS
Issue Type: Bug
Components: caching
Affects Versions: 2.7.1
Reporter: Yiqun Lin
In {{CacheAdmin}}, there are two places that not completely showing the cmd
usage message.
{code}
$ hdfs cacheadmin
Usage: bin/hdfs cacheadmin [COMMAND]
[-addDirective -path <path> -pool <pool-name> [-force] [-replication
<replication>] [-ttl <time-to-live>]]
[-modifyDirective -id <id> [-path <path>] [-force] [-replication
<replication>] [-pool <pool-name>] [-ttl <time-to-live>]]
[-listDirectives [-stats] [-path <path>] [-pool <pool>] [-id <id>]
[-removeDirective <id>]
[-removeDirectives -path <path>]
[-addPool <name> [-owner <owner>] [-group <group>] [-mode <mode>]
[-limit <limit>] [-maxTtl <maxTtl>]
{code}
The command {{-listDirectives}} and {{-addPool}} are not showing completely,
they are both lacking a ']' in the end of line.
In the {{CentralizedCacheManagement.md}}, there is also a similar problem. The
page of {{CentralizedCacheManagement}} can also showed this,
https://hadoop.apache.org/docs/r2.7.2/hadoop-project-dist/hadoop-hdfs/CentralizedCacheManagement.html
