Wei-Chiu Chuang commented on HDFS-11222:
----------------------------------------
I am not actually familiar with using curl to send webhdfs/httpfs requests. But
two things I noticed in the patch:
# mkdirs request should be sent via PUT method. It can't be sent via POST
method.
# If I send mkdirs via PUT to httpfs without Content-Type, my request is not
rejected.
# Looking at code (CheckUploadContentTypeFilter#doFilter), this should only
affect append and create, and when data=true. For example:
{noformat}
curl -i --negotiate -u : -X PUT
"http://ns1:14000/webhdfs/v1/tmp/bar3/abc?op=CREATE&data=true"; -H
'content-type: text/html'
{noformat}
# I verified the above command passes for webhdfs. So it's interesting there's
discrepancy between httpfs and webhdfs.
> Document application/octet-stream as required content type for HTTPFS PUT and
> POST
