-----------------------------------------
Summary: When Kerberos is enable encountering "Hit replay Buffer"
even if we increase replay buffer
Key: KNOX-595
URL: https://issues.apache.org/jira/browse/KNOX-595
Project: Apache Knox
Issue Type: Bug
Components: Server
Affects Versions: 0.5.0
Environment: All Linux environments using HDP latest release.
Reporter: Jeffrey E Rodriguez
Priority: Critical
Fix For: 0.7.0
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.
We are encountering an exception when loading large files:
