Subject [jira] [Created] (HDFS-4585) Webhdfs sometimes can't negotiate a SPNEGO token
Date Mon, 11 Mar 2013 20:25:13 GMT
Daryn Sharp created HDFS-4585:
---------------------------------

             Summary: Webhdfs sometimes can't negotiate a SPNEGO token
                 Key: HDFS-4585
                 URL: https://issues.apache.org/jira/browse/HDFS-4585
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: webhdfs
    Affects Versions: 2.0.0-alpha, 3.0.0, 0.23.7
            Reporter: Daryn Sharp


I'm not sure if this is a curl problem or webhdfs problem, but webhdfs will reject some users
because the Authorization header is too big.  In the case below, the header contains 4041
bytes, whereas a keytab user is generating 1745 bytes.  The failed user can use webhdfs via
"hadoop fs", but not via curl.

curl -v --negotiate -u : 'http://host/webhdfs/v1/?op=GETDELEGATIONTOKEN'
> GET /webhdfs/v1/?op=GETDELEGATIONTOKEN HTTP/1.1
> Authorization: Negotiate <<4041 bytes>>
> User-Agent: curl/7.19.5
> Host: host
> Accept: */*
> 
< HTTP/1.1 413 FULL head
< Connection: close
< Server: Jetty(6.1.26)
