NoSuchMethodError for org.apache.mesos.Protos$Value$Set.getItemList

[oubiwann]

This is a new one for me ... I'm not sure what has changed, but I wasn't getting this error last week :-/

(I might have still had an older jar file in my path, which would explain the sudden occurrence.)

When I kick off a new framework and the first resource offer is being processed, I get this error:

Exception in thread "Thread-7" java.lang.NoSuchMethodError: org.apache.mesos.Protos$Value$Set.getItemList()Lcom/google/protobuf/ProtocolStringList;

Looking at mesomatic.types, this is the code that seems to be bombing out:

(defmethod pb->data Protos$Value$Set
  [^Protos$Value$Set value-set]
 (set (.getItemList value-set)))

And, indeed, when I look at the Protobuf docs, I don't see this method defined for ProtocolStringList:

• https://developers.google.com/protocol-buffers/docs/reference/java/com/google/protobuf/ProtocolStringList

I'm not sure if Protos$Value$Set is supposed to be a ProtocolStringList or not ...

I've actually been running mesomatic 1.0.1-r0 against 1.0.0, so I'm going to download and build a new 1.0.1 before I continue debugging (just in case).

[oubiwann]

A new build of 1.0.1 gives me the same error. Will dig into this more tomorrow ...

Last night while falling asleep, I had the thought that this bug might actually be due to an inadvertent change by a calling function ... one that might now be passing an invalid data type.

If that turns out to be the case, I'll just close this as "invalid" ;-)

[oubiwann]

Found an issue (#34, potentially related?) and will test this issue against that fix when it's in place.

[oubiwann]

Another issue which may affect this one: #35.

[oubiwann]

Sweet -- with fixes in place for the two issues found above, the error for this ticket goes away.

Closing as a symptom, not an actual issue.
