我在启动Cassandra节点时遇到问题。 这是错误：
org.apache.cassandra.db.commitlog.CommitLogReadHandler$CommitLogReadException: Could not read commit log descriptor in file C:apache-cassandra-3_extractedapache-cassandra-3.10datacommitlogCommitLog-6-1497856002934.log

有谁知道我该如何开始？
这是在启动时读取提交日志的问题。您应该检查该文件是否可能为空或具有错误的权限。
如果您的集群上有多个节点 - 并且您的复制因子高于 1，只需删除此单个提交日志文件并尝试再次启动 cassandra 并运行修复即可。
这也适用于单节点或复制因子 1 - 但此日志文件中的更新插入会丢失数据。
