我按照
Install Cassandra安装cassandra的说明进行操作
当我安装时,我得到以下内容.我该怎么办？
service cassandra start xss = -ea -XX:+UseThreadPriorities -XX:ThreadPriorityPolicy=42 -Xms1001M -Xmx1001M -Xmn100M -XX:+HeapDumpOnOutOfMemoryError -Xss128k root@i-157-16647-VM:~# service cassandra status xss = -ea -XX:+UseThreadPriorities -XX:ThreadPriorityPolicy=42 -Xms1001M -Xmx1001M -Xmn100M -XX:+HeapDumpOnOutOfMemoryError -Xss128k * Cassandra is not running
我在一台有2台RAM的机器上运行.以下是我在虚拟机上安装的方法.
sudo vi /etc/apt/sources.list
#add sources.list

你的JAVA VM(128k)的分配内存用完了太小了.
修改下面的行(…“128k”…)以在文件中达到至少160k的堆栈大小
/opt/cassandra/conf/cassandra-env.sh或/etc/dse/cassandra/cassandra-env.sh
JVM_OPTS="$JVM_OPTS -Xss160k"
