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
> webhdfs api parameter validation should be better
