Yes I should.
According to documentation one should use BinaryMarshaller and keepBinary() 
together - https://apacheignite.readme.io/docs/binary-marshaller
Still ClassNotFoundException can be confusing for a newcomer.
I think we have to add fix suggestion for user who catch ClassNotFoundException 
with BinaryMarshaller and keepBinary=false

Is this sounds useful?

{noformat}
Suggestion for the cause of ClassNotFoundException
To disable, set -DIGNITE_QUIET=true
  ^-- Ignite configured to use BinaryMarshaller but keepBinary is false for 
request
  ^-- Server node need to load definition of data classes. It can be reason of 
ClassNotFoundException(consider IgniteCache.withKeepBinary to fix)
Refer this page for detailed information: 
https://apacheignite.readme.io/docs/binary-marshaller

[~NIzhikov],

It looks like you should use withKeepBinary() in case you want to scan with 
predicate.

[~avinogradov]

OK.
I will fix {{testEmptyScan}} issue in that way.

But what about {{testScanWithPredicate}}? 
Is test-case incorrect?
Seems like we can't use BinaryMarshaller and ScanQuery without explicit 
{{withKeepBinary()}}
It described in documentation \[1\] but can be confusing for a newcomer.
May be we need to add some kind of warning when executing requests with 
keepBinary=false for a Ignite configured with BinaryMarshaller?
Or detailed explanation of ClassNotFoundException for a specific case?

[~NIzhikov], 

Seems we can check that GridEventStorageManager -> lsnrs.get(evt.type()) is not 
null before unwrapBinaryIfNeeded(), this will be some kind of optimization and 
should solve issue.

> Is it possible to send event without unmarshalling

Yes, It possible.
{{cache.withKeepBinary()}} make keepBinary flag true for all type of requests.
Values doesn't unwrap on remote nodes when keepBinary=true.

> do not unmarshal in case no one subscribed?

Current implementation doesn't check if there is any listeners when unwrapping 
data for a event.
I think such check would be useful.
But it doesn't help for a {{testScanWithPredicate}} from my test-case in 
previous post.
Because data would be unmarshalled for a {{IgniteBiPredicate.apply}} call

[~avinogradov],
Are sure for this case needed to deserialize this value? If nobody subscribe 
this event might be make sense to doesn't unmarshal a value. What do you think 
about it?

Hello.

Some conclusions about this issue:

1. With BinaryMarshaller keepBinary value is false for all types of requests 
from client node to server node.
One can change default behavior with IgniteCache.withKeepBinary call.
2. If we using default configuration from test framework(i.e. IncludeEventTypes 
= EventType.EVTS_ALL) server node try to unwrap BinaryObject when executing 
ScanQuery.
for recording event EVT_CACHE_QUERY_OBJECT_READ.
This leads to ClassNotFoundException on server node.

How should I fix this issue?

Test to reproduce Exception:

{code:java}
package org.apache.ignite.internal.processors.cache;

import org.apache.ignite.configuration.IgniteConfiguration;
import org.apache.ignite.events.EventType;

public class IgniteCacheBinaryObjectsScanSelf2Test extends 
IgniteCacheBinaryObjectsScanSelfTest {
/** {@inheritDoc} */
@Override protected IgniteConfiguration getConfiguration(String 
igniteInstanceName) throws Exception {
IgniteConfiguration cfg = super.getConfiguration(igniteInstanceName);
cfg.setIncludeEventTypes(EventType.EVTS_ALL);
return cfg;
}
}

Hi.

I investigate this issue.
Here is result;

# Attached ScanQueryBug runs OK on 2.0.0 release. So bug seems not reproducible
# I wrote test to make sure bug is not reproducible - 
https://github.com/nizhikov/ignite/pull/2
# Test succeed with OptimizedMarshaller
# Test fails with BinaryMarshaller.

Should I fix BinaryMarshaller is this issue or open another?

Here is stack trace:

The issue is still reproduced even after IGNITE-2178 has been fixed.

Attached a reproducible example that was executing again ignite-1.5 branch.
