[IGNITE-13553] Node failure with ClassNotFoundException when indexed field of QueryEntity differs from type used in put operation

• Type: Bug

• Priority: Blocker
• Resolution: Fixed
• Affects Version/s: 2.9, 2.8.1, 2.10
• Fix Version/s: 2.9

Description

Failures occur under these conditions:

1. Data classes are not present in server classpaths, peer-classloading is not used because thin client is used.
2. Manual construction of QueryEntity via #setFields, #setIndexes etc. is used instead of constructor of QueryEntity in conjunction with @QuerySqlField for data clases.
3. One of the indexed fields of QueryEntity has type different from type of corresponding field of data object instance, eg:
   QueryEntity

   fields.put("name", "java.lang.String");
   fields.put("wrongTypeEmbeddable", "java.lang.String"); /* This is wrong type */
   
   QueryEntity qryEntity = new QueryEntity()
   	.setKeyType("java.lang.Integer")
   	.setValueType("org.apache.ignite.wrongtype.WrongTypeEntity") /* FQDN should be used */
   	.setFields(fields)
   	.setIndexes(Collections.singleton(
   		new QueryIndex("wrongTypeEmbeddable") /* Wrong type field is indexed */));
   

   Embedded field type in put operation is different

   cache.put(0, new WrongTypeEntity("name",
   	new WrongTypeEmbeddable(256, "testField") /* wrongTypeEmbeddable field */));
   

How to reproduce:

1. Start server nodes with default config via ignite.sh
2. Run reproducer.

For Apache Ignite 2.8.1 failures are identical for atomic and transactional caches:

[17:45:23,108][SEVERE][sys-stripe-0-#1][] JVM will be halted immediately due to the failure: [failureCtx=FailureContext [type=CRITICAL_ERROR, err=class o.a.i.binary.BinaryInvalidTypeException: o.a.i.wrongtype.WrongTypeEmbeddable]]

For AI, built and assemblied from master, failure is supressed for atomic and occur only for transactional caches:

[17:39:09,305][SEVERE][sys-stripe-10-#11][] JVM will be halted immediately due to the failure: [failureCtx=FailureContext [type=CRITICAL_ERROR, err=class o.a.i.i.transactions.IgniteTxHeuristicCheckedException: Committing a transaction has produced runtime exception]]

Root cause for all failures is:

Caused by: java.lang.ClassNotFoundException: org.apache.ignite.wrongtype.WrongTypeEmbeddable
