-------------------------------------
Summary: Scheduler HTTP API cuts JSON buffers
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 prefixed
with a string like `4f7e-0020`:
