------------------------------------
Summary: Cleanup TaskManager initialization logic
Key: FLINK-1580
URL: https://issues.apache.org/jira/browse/FLINK-1580
Project: Flink
Issue Type: Bug
Reporter: Till Rohrmann
Currently, the TaskManager initializes many heavy load objects upon
registration at the JobManager. If an exception occurs during the
initialization it takes quite long until the {{JobManager}} detects the
{{TaskManager}} failure.
Therefore, it would be better if we could rearrange the initialization logic so
that the {{TaskManager}} only registers at the {{JobManager}} if the all
objects could be initialized successfully. Moreover, it would be worthwhile to
move some of the initialization work out of the {{TaskManager}}.
