Question

当我将xml文件写入Cassandra表列时，我面临以下异常。它是一个3节点集群，所有节点都已启动。

com.datastax.driver.core.exceptions.WriteFailureException: Cassandra failure during write query at consistency LOCAL_QUORUM (2 responses were required but only 0 replica responded, 1 failed)

如果有人帮助我摆脱这种情况，那就太好了。感谢

然而，我不知道真正的解决方案。

群集节点var / log / cassandra / system.log文件之一。我发现sstable损坏了一张桌子。该表用于抛出异常的代码。

备份表格。从节点中删除损坏的db文件。掉落表。重新创建表。

这对我有用。
