Question

我在Mac上使用brew安装了Cassandra，它工作正常几天。但现在它开始抛出错误而不改变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")})

所以我尝试使用brew更新Cassandra到3.11。现在，在启动Cassandra时，我收到了这个错误。

从此链接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。但即使节点工具修复也无法正常工作。

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已损坏。删除该文件，然后重新启动。

＆＃34;但即使节点工具修复也无效。＆＃34;

我不担心。如果您使用单个节点群集（例如：您自己的Mac），则修复没有任何其他节点来传输数据，因此无论如何都无法工作。

Cassandra 3.11抛出错误＆＃34;在初始化期间处理提交日志时因错误而退出＆＃34;
