Hi Theyaa, Change the size of gateway.httpserver.requestHeaderBuffer property. I think the default is 8912 (8k) change to 16384. See if that helps.
For the second problem Request is a replay (34))] this message is often seen when the timing of one of the servers is off. Make sure you use NTPD on all servers and they are all in sync. If everything is in sync you can work around this issue by turning off krb5 replay cache. With the following parameter -Dsun.security.krb5.rcache=none dav On 10/9/18, 9:01 AM, "Theyaa Matti" <theyaama...@gmail.com> wrote: Hi, I am getting this error message "WARN HttpParser: Header is too large >8192" when trying to access the spark history ui through knox.
