Alejandro Abdelnur commented on HADOOP-8816:
--------------------------------------------
128K as header buffer size seems a bit too big.
Could this be related to this?

Would be possible to get the actual header size that is making things to fail?

> Project: Hadoop Common
> Issue Type: Bug
> Components: net
> Affects Versions: 2.0.1-alpha
> Environment: ubuntu linux with active directory kerberos.
> Reporter: Moritz Moeller

> The HTTP Authentication: header is too large if using kerberos and the

> limit.
> Can be fixed by adding ret.setHeaderBufferSize(1024*128); in
> org.apache.hadoop.http.HttpServer.createDefaultChannelConnector
