版本：doris-manager-24.0.0
升级操作：doris2.1.4（使用doris-manager安装）升级到2.1.5
问题：升级过程，在【启动BE节点】环节报错，启动be失败，报错如下：
time="2024-07-24T17:53:06.455+08:00" level=error msg="failed to run command to start be node, failed to run serial command
/service/doris/apache-doris-bin/be/bin/start_be.sh --daemon, exit status 1, output: The JAVA_HOME environment variable is not defined correctly\nThis environment variable is needed to run this program\nNB: JAVA_HOME should point to a JDK not a JRE\nYou can set it in be.conf\n"
问题分析：
java8是manager自己下载的，测试正常，fe.conf配置也正常

问题解决
在be.conf文件末尾增加一个空行，就可以启动成功了。
doris-manager在升级时，会注释掉原来的JAVA_HOME然后在文件末尾增加JAVA_HOME,不知道为什么JAVA_HOME出现在最后一行会导致JAVA_HOME should point to a JDK not a JRE\nYou can set it in be.conf
关键日志如下：
