------------------------------------
Summary: It's not possible to mix limit and attribute constraints
Key: AURORA-199
URL: https://issues.apache.org/jira/browse/AURORA-199
Project: Aurora
Issue Type: Bug
Components: Client
Reporter: brian wickman
A user had a valid need for the following use-case:
{noformat}
constraints = {
'host': 'hostname1',
'host': 'limit:2'
}
{noformat}
in order to pin 2 instances of a job to the same host. Pystachio Map is a
multimap but it gets coerced to a Python dictionary when converting to a set of
Thrift Constraint objects, and the 'multi-' part of the mapping is lost.
We should probably add a new delimiter, e.g. ';' in order to allow for mixes of
limit and attribute constraints, e.g. 'host': 'hostname1;limit:2'
