Tom White commented on HADOOP-6974:
-----------------------------------

This looks good. Do we need a test that checks that the request fails for a cookie that is bigger than the header buffer?

> 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.
