但cassandra启动执行仍在继续。最后我得到了例外

但种子节点正在运行。

禁用机器防火墙。

我也尝试更改默认的tmp目录。我尝试将JVM_OPTS = -Dorg.xerial.snappy.tempdir = / tmp包含在cassandra.in.sh文件中，但问题仍然存在。

Linux版本2.6.32-358.6.1.el6.x86_64（mockbuild@c6b9.bsys.dev.centos.org）（gcc版本4.4.7 20120313（Red Hat 4.4.7-3）（GCC））＃ 1 SMP Tue Apr 23 19:29:00 UTC 2013

请帮助我..提前谢谢。

Answer 1

他们在Cassandra JIRA中提到了这个错误： https://issues.apache.org/jira/browse/CASSANDRA-4400

我和Cassandra 1.2有类似的错误，我通过用snappy 1.0.4.1替换snappy 1.0.5库来修复它。如果该链接不起作用，您应该能够从早期版本的Cassandra（如1.1.x）中获取该链接。

基本上，从$CASSANDRA_HOME/lib目录中删除snappy-java.1.0.5.jar，并将其替换为snappy-java-1.0.4.1.jar

Answer 2

我找到了Erik写的答案 http://mail-archives.apache.org/mod_mbox/cassandra-user/201312.mbox/%3C52C1DEC4.2080904@cj.com%3E

你可以在cassandra-env.sh中添加这样的东西：

JVM_OPTS =＆＃34; $ JVM_OPTS -Dorg.xerial.snappy.tempdir = /路径/该/允许/可执行＆＃34;

我在/ var / lib / cassandra /

中创建了一个tmp文件夹

所以我添加了

JVM_OPTS =＆＃34; $ JVM_OPTS -Dorg.xerial.snappy.tempdir = / var / lib / cassandra / tmp /＆＃34;

希望这有帮助的人
