---------------------------------
Summary: Type mismatch in ReadClusterState's ProfileAction
processing Map
Key: STORM-2345
URL: https://issues.apache.org/jira/browse/STORM-2345
Project: Apache Storm
Issue Type: Bug
Components: storm-core
Affects Versions: 2.0.0, 1.0.3, 1.x
Reporter: Tibor Kiss
Assignee: Tibor Kiss
Priority: Trivial
Discovered during reading STORM-2018's review comments:
{{ReadClusterState.run()}} method loads all the profiling requests from Zk then
filters the ones designated to that particular node it runs on.
The filtered profiling requests are stored in a Map: {{Map<Integer,
Set<TopoProfileAction>>}} on a per Slot basis.
For some reason the TCP Port is serialized as i64/Long in NodeInfo, which is
later used as a key in the Map.
The Map.put is converted properly to Integer, but the Map.get does not, causing
the lookups to report a miss in the {{filtered}} Map.
This could cause TopoProfileActions ignored if one would send multiple
TopoProfileActions through Zk.
I don't think that could normally happen (using the UI), but the fix is trivial.
