Alejandro Abdelnur commented on HDFS-4585: ------------------------------------------ This was an issue before HADOOP-8816, do you still see it a cluster with HADOOP-8816? AFAIK hadoop-auth is doing SPNEGO correctly, this prob was because Jetty was not configure with a big enough header buffer. > 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.
