Secure Oozie POST/PUT Request Payload Size Restriction With one exception there are no known size limits for requests or responses payloads that pass through the gateway. The exception involves POST or PUT request payload sizes for Oozie in a Kerberos secured Hadoop cluster. In this one case there is currently a 4Kb payload size limit for the first request made to the Hadoop cluster. This is a result of how the gateway negotiates a trust relationship between itself and the cluster via SPNEGO. There is an undocumented configuration setting to modify this limit’s value if required. In the future this will be made more easily configurable and at that time it will be documented.
