Vinod Kone commented on MESOS-5567:
-----------------------------------
I think what you are seeing is HTTP chunked transfer encoding in play. Your
application/library needs to keep reading more data until it reads the number
of bytes specified at the beginning (in your example it is 1983 bytes) to read
the full JSON for an event .

> Key: MESOS-5567
> URL: https://issues.apache.org/jira/browse/MESOS-5567
> Project: Mesos
> Issue Type: Bug
> Components: HTTP API
> Affects Versions: 0.28.1
> Environment: Ubuntu 14.04 latest
> Reporter: Tobias Mueller
>
> According to the docs at
> http://mesos.apache.org/documentation/latest/scheduler-http-api/ I assumed
> that the message format would only contain "full" (meaning parseable) JSON
> messages. In fact, I'm partially seeing splitted JSONs, where the next chunk
> is just continuing the first part:
> {noformat}
