当我尝试在 cqlsh 中使用帮助命令时，出现段错误:
Connected to Test Cluster at localhost:9160.
[cqlsh 4.0.1 | Cassandra 2.0.1 | CQL spec 3.1.1 | Thrift protocol 19.37.0]
Use HELP for help.

Segmentation fault: 11
Cassandra 是使用自制软件安装的。 Java版本:
java version "1.7.0_17"
Java(TM) SE Runtime Environment (build 1.7.0_17-b02)
Java HotSpot(TM) 64-Bit Server VM (build 23.7-b01, mixed mode)
我尝试更改 cassandra-env.sh 中的每个线程堆栈大小。
我尝试过的值:256k、300k、512k、1024k。
我通过执行命令验证 cassandra 使用这些值:
cassandra -f
堆栈大小为 300k 的输出:
xss = -ea -javaagent:/usr/local/Cellar/cassandra/2.0.1/jamm-0.2.5.jar -XX:+UseThreadPriorities -XX:ThreadPriorityPolicy=42 -Xms4G -Xmx4G -Xmn800M -XX:+HeapDumpOnOutOfMemoryError -Xss300k
我使用的是 OS X Mavericks，如果相关的话我有 16 GB RAM。
编辑:
我在使用 cassandra-cli 时没有遇到类似的问题。
根据 Nikolai Grigoriev 的建议，我查看了系统日志:
cat system.log | tail -n 20
相关输出:

我从源头获取了 Cassandra 的发行版。问题仍然存在。这真的是 JVM 错误吗？
如何解决这个问题？
已解决
这不是 JVM 错误。我使用 pythonbrew 来管理 python 解释器(忘了提及)。当我在全局解释器上安装 cql 时，一切都很顺利。显然 python 路径存在一些问题。然后在使用 Cassandra 时我将使用全局 python 解释器。
我将问题范围缩小到了 pythonbrew。难怪它被弃用了。我使用 pyenv 时没有出现段错误。
最佳答案
运行 cqlsh 时，我遇到了类似的问题，Python 在 OS X 10.9.5 上崩溃。
解决方案是安装 https://www.python.org/ftp/python/2.7.9/python-2.7.9-macosx10.6.pkg
关于macos - Cassandra:Mac 上的 cqlsh 段错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/19663493/
