安装Cassandra时出现错误

Question

尝试在本地系统中安装Cassandra时出现以下错误。你能帮我解决这个错误吗？

WARN  [main] 2021-04-22 19:23:16,688 StartupChecks.java:220 - The JVM is not configured to stop on OutOfMemoryError which can cause data corruption. Use one of the following JVM options to configure the behavior on OutOfMemoryError:  -XX:+ExitOnOutOfMemoryError, -XX:+CrashOnOutOfMemoryError, or -XX:OnOutOfMemoryError="<cmd args>;<cmd args>"

Answer 1

这些并不是错误--它们只是一些未配置参数的警告，并建议您可以配置一些选项。具体来说，您可以忽略第二行(关于JMX)，但最后一行更重要-打开conf/jvm.options并添加带有-XX:+ExitOnOutOfMemoryError选项的行。
