[jira] [Created] (STORM-3687) MetricsConsumer has
ClassCastException on a mixed cluster
Ethan Li created STORM-3687:
-------------------------------
Summary: MetricsConsumer has ClassCastException on a mixed cluster
Key: STORM-3687
URL: https://issues.apache.org/jira/browse/STORM-3687
Project: Apache Storm
Issue Type: Bug
Reporter: Ethan Li
During rolling upgrade, some supervisors are still at 2.2, and others are running on 2.3. So some workers are running with storm-client-2.2.jar and others are on 2.3.
Because of https://github.com/apache/storm/commit/93a7f770d508668bc7af183e08535813fff6f805 (STORM-3660)
the "_credentials" stream is removed.
So the map of streamId to streamName for system component is changed
refer to the code at:
https://github.com/apache/storm/blob/v2.2.0/storm-client/src/jvm/org/apache/storm/serialization/SerializationFactory.java#L218-L222
So a worker running on storm-client-2.2 might send out __metrics from its systembolt, while the MetricsConsumer running with storm-client-2.3 interprets it as "__metrics_tick" because the mapping is different:
{code:java}
o.a.s.s.SerializationFactory Thread-15-__system-executor[-1, -1] [INFO] idmap for system comp {__tick=6, __system=5, __metrics_tick=4, __credentials=1, __flush=2, __metrics=3}
{code}
vs
{code:java}
o.a.s.s.SerializationFactory Netty-server-localhost-6703-worker-1 [INFO] idmap for system comp {__tick=5, __system=4, __metrics_tick=3, __flush=1, __metrics=2}
{code}
Hence we see
{code:java}

{code}
Since mixed cluster is not guaranteed to work, I am not going to fix this for now. But will add some warnings in the code so people can be aware of it.
