Andrew Wang created HDFS-5565:
---------------------------------
Summary: CacheAdmin help should match against non-dashed commands
Key: HDFS-5565
URL: https://issues.apache.org/jira/browse/HDFS-5565
Project: Hadoop HDFS
Issue Type: Sub-task
Components: caching
Affects Versions: 3.0.0
Reporter: Andrew Wang
Priority: Minor
Using the shell, `hdfs dfsadmin -help refreshNamespace` returns help text, but
for cacheadmin, you have to specify `hdfs cacheadmin -help -addDirective` with
a dash before the command name. This is inconsistent with dfsadmin, dfs, and
haadmin, which also error when you provide a dash.
