spurthicriteo opened a new pull request #11923:
URL: https://github.com/apache/flink/pull/11923
## What is the purpose of the change
[FLINK-17401] Currently labels are not set in the task info object. A lot
of companies can have logic specific to labels on TM. For example in criteo,
based on labels we set kerberos env variables and mesos debug capabilities. It
is critical for us to be able to pass these label values to the task manager.
## Brief change log
Reading the labels as map structure from flink config and pass it to mesos
task parameters. TaskInfo object is populated with the labels by
LaunchableMesosWorker.
