Subject [jira] [Commented] (HDFS-2428) webhdfs api parameter validation should be better
Date Tue, 11 Oct 2011 00:46:29 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2428?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13124613#comment-13124613
] 

Arpit Gupta commented on HDFS-2428:
-----------------------------------

Rename request leads to a 500 when the dstPath is null. We should return a 400


{code}
Request URI http://NN:50070/webhdfs/tmp/webhdfs_data/dir_with_children_to_be_renamed?op=RENAME&dstPath=
Request Method: PUT
Status Line: HTTP/1.1 500 Internal Server Error
Response Content: {"RemoteException":{"className":"java.lang.IllegalArgumentException","message":"Can
not create a Path from a null string"}}
{code}

The content is correct but we should return a 400 instead of a 500
