--------------------------------------
Summary: Thermos Observer Takes up to 150% CPU on default settings
Key: AURORA-1481
URL: https://issues.apache.org/jira/browse/AURORA-1481
Project: Aurora
Issue Type: Bug
Affects Versions: 0.9.0
Environment: CentOS 6.6 w/ Mesos 0.22.0
Reporter: Paul Cavallaro
Priority: Minor
The Thermos Observer when default configured with 5 second polling interval
takes up to 150% cpu on an aws c3.4xlarge. This is with
~10k executors
~1 run per executor
Haven't done any profiling, but the overall design seems to be inefficient
given it has to list read the entire directory tree every time and do a fair
amount of regex parsing.
