无法使用bin/cassandra启动Cassandra db

Question

我有Ussntu 12.04和cassandra 1.1.3(tarball安装),当我尝试启动cassandra时,我得到以下内容:

user@ubuntu:~/apache-cassandra-1.1.3/bin$ sudo ./cassandra -f
xss =  -ea -javaagent:./../lib/jamm-0.2.5.jar -XX:+UseThreadPriorities -XX:ThreadPriorityPolicy=42 -Xms4G -Xmx4G -Xmn800M -XX:    +HeapDumpOnOutOfMemoryError -Xss128k
user@ubuntu:~/apache-cassandra-1.1.3/bin$ 

根据cassandra文档,输出看起来不像预期的那样:

The service should start in the foreground and log gratuitously to 
standard-out. Assuming you don't see messages with scary words like  
"error", or "fatal", or anything that looks like a Java stack trace,  
then chances are you've succeeded.

那么,问题是什么？

问题可能是由于使用OpenJDK引起的,如Cassandra错误报告中所述,但是,请参阅此处有关Sun/Oracle和其他JVM上此问题的注释:

• https://issues.apache.org/jira/browse/CASSANDRA-2441

如果无法安装Oracle JVM,请尝试在配置脚本中更改堆栈大小conf/cassandra-env.sh.在第185行左右查找以下部分,并将其更改-Xss180k为更高的值.

if [ "`uname`" = "Linux" ] ; then
  # reduce the per-thread stack size to minimize the impact of Thrift
  # thread-per-client.  (Best practice is for client connections to
  # be pooled anyway.) Only do so on Linux where it is known to be
  # supported.
  # u34 and greater need 180k
  JVM_OPTS="$JVM_OPTS -Xss180k"
fi
echo "xss = $JVM_OPTS"

在Rackspace和Amazon的Ubuntu服务器上测试安装时,我成功使用了280k.

根据下面评论中的报告,我建议以20k为增量增加堆栈大小,从开始-Xss200k,直到Cassandra正常启动.请注意,也可以删除此选项并使用每个线程的默认堆栈大小,但请注意这将对内存消耗产生的影响.
