Subject [jira] [Commented] (HDFS-4456) Add concat to WebHDFS REST API
Date Thu, 31 Jan 2013 23:07:14 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4456?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13568220#comment-13568220
] 

Plamen Jeliazkov commented on HDFS-4456:
----------------------------------------

Alejandro, @SuppressWarnings("unchecked") is not possible because we are doing assignments
inside of a put method in a static block.

private static final Map<Enum, ClassParam<?>[]> PARAMS_DEF =
    new HashMap<Enum, Class<Param<?>>[]>();

static {
  PARAMS_DEF.put(Operation.CONCAT, new Class[]{SourcesParam.class});
}

I cannot add <Param<?>> to the Class array to solve the issue, nor can I add the
suppression above the static block or above the put call.

I have however been able to remove the issue by removing Generics on the classes. I will give
you both patches -- the first one will be without the removal of Generics, meaning there will
be a -1 on the javac report. The second patch will have the removal in place and fix javac
errors.
