He Yongfu commented on IGNITE-1190:
-----------------------------------

When I run CacheJdbcStoreExample ,the peer server the following error:
class org.apache.ignite.IgniteCheckedException: Failed to send response to node. Unsupported direct type [message=GridCacheQueryRequest [id=5, cacheName=PERSON, type=SCAN, fields=false, clause=null, clsName=null, keyValFilter=null, rdc=null, trans=null, pageSize=1024, incBackups=false, cancel=false, incMeta=false, all=false, keepPortable=false, subjId=040e11fa-c970-46d9-b7a6-27aebf2772cf, taskHash=0, part=-1, super=GridCacheMessage [msgId=6, depInfo=null, err=class org.apache.ignite.IgniteCheckedException: Failed to find class with given class loader for unmarshalling (make sure same version of all classes are available on all nodes or enable peer-class-loading): org.apache.ignite.internal.processors.cache.GridCacheDeploymentManager$CacheClassLoader@896c352, skipPrepare=false]]]
