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. -- This message was sent by Atlassian JIRA (v6.1#6144)
