Tom Petr created MESOS-5060:
-------------------------------
Summary: Requesting /files/read.json with a negative length value
causes subsequent /files requests to 404.
Key: MESOS-5060
URL: https://issues.apache.org/jira/browse/MESOS-5060
Project: Mesos
Issue Type: Bug
Affects Versions: 0.23.0
Environment: Mesos 0.23.0, CentOS 6
Reporter: Tom Petr
Priority: Minor
I accidentally hit a slave's /files/read.json endpoint with a negative length
(ex. http://hostname:5051/files/read.json?path=XXX&offset=0&length=-100). The
HTTP request timed out after 30 seconds with nothing relevant in the slave
logs, and subsequent calls to any of the /files endpoints on that slave
immediately returned a HTTP 404 response. We ultimately got things working
again by restarting the mesos-slave process (checkpointing FTW!), but it'd be
wise to guard against negative lengths on the slave's end too.
