Hive进程内存大小

Question

请帮助我理解Hive上下文中512mb（粗体大小）的内容是什么？ 它的内存大小是多少？ 我在export HADOOP_HEAPSIZE=4192文件中设置了hive-site.xml

hadoop@master:~/hive/conf$ ps -ef | grep 'hive'

您编辑的变量适用于客户端，而不是服务器，并且您不会从XML文件中导出任何内容

  

要配置HiveServer2和Hive Metastore的堆大小，请将HADOOP_OPTS变量中的-Xmx参数设置为/etc/hive/hive-env.sh

中所需的最大堆大小

VS

  

要配置Beeline CLI的堆大小，请在HADOOP_HEAPSIZE

中设置/etc/hive/hive-env.sh环境变量

除此之外，这两个值都是如此，所以你可能想看看
