Cassandra 3.11抛出错误“初始化期间处理提交日志时由于错误退出”

Question

我用brew在mac上安装了Cassandra，几天来一直运行良好。但是现在它开始抛出错误，而不更改yaml文件中的任何内容。

Connection error: ('Unable to connect to any servers', {'127.0.0.1': error(61, "Tried connecting to [('127.0.0.1', 9042)]. Last error: Connection refused")})

所以我试着用brew更新Cassandra到3.11。现在启动卡桑德拉时，我得到了这个错误。

通过这个链接Cassandra: Exiting due to error while processing commit log during initialization，我得到了一些关于节点工具修复的信息。但即使是节点工具的修复也不起作用。

objc[15089]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.8.0_111.jdk/Contents/Home/bin/java (0x10934b4c0) and /Library/Java/JavaVirtualMachines/jdk1.8.0_111.jdk/Contents/Home/jre/lib/libinstrument.dylib (0x10abba4e0). One of the two will be used. Which one is undefined.

Answer 1

commit log /usr/local/var/lib/cassandra/commitlog/CommitLog-6-1505888222471.log

听起来你的一个提交日志文件被破坏了。删除该文件，然后重新启动。

“但即使是节点工具修复也不起作用。”

我不会担心这个的。如果您是在单个节点集群上(例如:您自己的Mac)，那么修复就没有任何其他节点可用于流数据，因此无论如何它都无法工作。
