请问你能帮我理解Hive上下文中的512mb（以粗体显示）吗？它的内存大小是多少？我在 hive-site.xml 文件中设置了 export HADOOP_HEAPSIZE=4192

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

hadoop 5587 1 0 Feb14？ 00:05:27 / usr / lib / jvm / default-jdk / bin / java -Xmx4192m -Djava.net.preferIPv4Stack = true -Dhadoop.log.dir = / home / hadoop / hadoop-2.7.3 / logs -Dhadoop .log.file = hadoop.log -Dhadoop.home.dir = / home / hadoop / hadoop-2.7.3 -Dhadoop.id.str = hadoop -Dhadoop.root.logger = INFO，console -Djava.library.path = /home/hadoop/hadoop-2.7.3/lib/native -Dhadoop.policy.file = hadoop-policy.xml -Djava.net.preferIPv4Stack = true -Xmx512m -Dhadoop.security.logger = INFO，NullAppender org.apache . hadoop.util.RunJar /home/hadoop/hive/lib/hive-metastore-2.3.2.jar org.apache.hadoop.hive.metastore.HiveMetaStore

    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，请在/etc/hive/hive-env.sh中将HADOOP_OPTS变量中的-Xmx参数设置为所需的最大堆大小

    VS

    要配置Beeline CLI的堆大小，请在/etc/hive/hive-env.sh中设置HADOOP_HEAPSIZE环境变量

    除此之外，这两个值都是如此，所以你可能想看一下
