Mesos task - Failed to accept socket: future disca

问题:

I am just trying to upgrade mesos version to 1.3.1 from 1.0.3.

Chronos scheduler is able to schedule the JOB thru mesos. The job runs fine and able to see mesos stdout logs. But, still seeing the following in mesos stderr logs. The docker jobs runs fine, but still the status is showing as failed with the below logs.

Do not worry. This line was introduced in 1.3 by r/58557/ and will be fixed in 1.4

This log line is not usually a problem, and reporting it as an error can cause needless debugging. r/59817
