Re: Iginte - Exception - Failed to unmarshal discovery data for component: 1 - on starting server from console and an application in eclipse IDE

Hi,

It looks like the application has Geronimo JCache spec [1] on the classpath.
It's fully compatible with the original JCache spec on API level, but there
are different serial versions on some of serializable classes. Please make
sure that the same version is used on everywhere in the cluster.

In case you're using Maven, replacing Geronimo dependency with the the
following should help:


javax.cache
cache-api
1.0.0

As I know JdkMarshaller used for serialization of internal ignite objects,
such as continuous query, distributed services etc., not for cache entries.

In your case the exception occured during deserialization of object
javax.cache.configuration.MutableConfiguration.
This class is from cache-api library. Ignite use version 1.0.0 of this
library. In this version the class MutableConfiguration has serialVersionUID
= 201306200821L.
Your sample app in eclipse used some other version of cache-api
(MutableConfiguration has serialVersionUID = 201405).
This cause of exception.

I will definitely let you know if I can reproduce it, but just for my own 
understanding, as you saw in the sample, I was just storing strings, so what 
could have caused the serialization exception?  Just want to avoid misusing the 
API.

 Hi,

For internal activities ignite use only work directory.
Let me know if the issue is reproduced again.

Hi M Singh!

I can't reproduce this. Could you provide your eclipse project?
