> Based on the current design for delegation token in secure Router, the total
> number of tokens store and update in zookeeper using
> ZKDelegationTokenManager.
> But the default value of system property `jute.maxbuffer` is just 4MB, if
> Router store too many tokens in zk, it will throw IOException `{{{}Packet
> lenxx is out of range{}}}` and all Router will crash.
>
> In our cluster, Routers crashed because of it. The crash logs are below
