  • Janusgraph org.apache.tinkerpop.gremlin.driver.exception.ResponseException: Error during serialization: Could not execute operation due to backend exception

    项目里使用的图数据Cassandra+Elasticsearch+JanusGraph,代码没动过,忽然有的查询报错org.apache.tinkerpop.gremlin.driver.exception.ResponseException: Error during serialization: Could not execute operation due to backend exception

    分析:数据库本身出问题了,让数据组的小伙伴帮忙检查节点是不是有挂掉的,最后发现有一个Cassandra节点没起,启动该节点,问题解决
