------------------------------------
Summary: Failed to read class name from file on deserialization
Key: IGNITE-2965
URL: https://issues.apache.org/jira/browse/IGNITE-2965
Project: Ignite
Issue Type: Bug
Components: general
Reporter: Semen Boikov
Priority: Critical
Fix For: 1.6
I added test MarshallerCacheJobRunNodeRestartTest from time to reproducing
error 'Failed to read class name from file' during during deserialization.
This is some issue with marshaller cache: it is updated usign putIfAbsent
method, now its implementation has a race and sometimes it can exit before
value is updated on backup node. As a workaround for marshaller cache I usggest
using 'getAndPut' instead of 'putIfAbsent (just need implement 'tryGetAndPut'
method which will not wait for topology changes).
Also let's make error message in MarshallerContextImpl.className more
informative.
