Question

我正在使用Apache Ignite并尝试使用SqlFieldsQuery加入多个缓存。如果其中一个缓存有200万条记录，则会抛出以下异常：

Exception in thread "main" javax.cache.CacheException: Failed to run map query remotely.
    at org.apache.ignite.internal.processors.query.h2.twostep.GridReduceQueryExecutor.query(GridReduceQueryExecutor.java:652)

我该如何解决这个问题？

您应该检查标识为b72073a8-e58e-4998-9ae5-fc4abf05a800的节点的日志。应该有一个导致失败的例外。

连接具有大量条目的表会引发异常
