> If you try to use the Oozie CLI in a Kerberized environment with a user in a
> lot of groups (e.g. the groups list is 30+ lines), all commands fails with
> {noformat}
> Error: AUTHENTICATION : Could not authenticate, Authentication failed,
> status: 400
> {noformat}
> We need to increase the {{maxHttpHeaderSize}} that Tomcat allows from the
> default, 8192 (8K), to 65536 (64K).
