-------------------------------------------
Hi Chandana.
I haven't had the chance to try this patch.
One thing you need to consider is that in your case the issue in IOP is on
release 0.6.0 of Knox. The patch is on current release of Knox.
Regards,
Jeff

> When Kerberos is enable, even if the application doesn't support SPNEGO we go
> through ExecuteKerberosDispatch. When we follow this path Knox uses a
> CappedBufferHttpEntity. I presume to replay entities once SPNEGO protocol
> figures out whether app supports SPNEGO or not.
