Improve fault-tolerance of DemuxManager.
----------------------------------------
Key: CHUKWA-534
URL: https://issues.apache.org/jira/browse/CHUKWA-534
Project: Chukwa
Issue Type: Improvement
Reporter: Bill Graham
Assignee: Bill Graham
If the DemuxManager received more than 5 consecutive errors, it dies with the
message "Too many errors, Bail out!".
Let's change to this introduce a configurable number of concurrent exceptions
to be encountered before dying. If the value is set to -1, expected behavior is
to keep retrying ad infinitum.
Also as part if this bug is to improve logging of how many consecutive errors
have occurred, as well as the time they started. A possible future enhancement
could be to support an error time threshold as well as an absolute count.
Suggesting the following new config setting. It's a bit verbose, but it's clear.
