Paul Butler commented on HADOOP-6974:
-------------------------------------
Tom, I've remade the patch to work against trunk. I haven't added tests for
larger headers, but if the consensus is that that's necessary, I can do so.
> Configurable header buffer size for Hadoop HTTP server

> URL: https://issues.apache.org/jira/browse/HADOOP-6974
> Project: Hadoop Common
> Issue Type: Improvement

> This patch adds a configurable parameter dfs.http.header.buffer.size to
> Hadoop which allows the buffer size to be configured from the xml
> configuration.
> This fixes an issue that came up in an environment where the Hadoop servers
> share a domain with other web applications that use domain cookies. The large
> cookies overwhelmed Jetty's buffer which caused it to return a 413 error.
