Subject [jira] [Commented] (HDFS-12030) Ozone: CLI: support infoKey command
Date Wed, 28 Jun 2017 15:44:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12030?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16066736#comment-16066736

Weiwei Yang commented on HDFS-12030:

Hi [~linyiqun]

I see. I actually was expecting something like your v1 patch as that respects the API design.
But I doubt if getKey would still work if you give a default value to query parameter "info"

+                  @DefaultValue(Header.OZONE_LIST_QUERY_KEY)
+                  @QueryParam(Header.OZONE_LIST_QUERY_TAG)

you may want to double check.

bq. I am thinking if there is one way we can handle this in different processor meanwhile
keep the url path not changed?

As far as I know the http request is dispatched to java handlers only by the *path*, not parameters.
So probably if the GET requests use same path, they will be always routed to one handler.
I am not sure how to address [~xyao]'s comment in such case, maybe he can us a hint.
