记一次dolphinscheduler堆内存溢出 java.lang.OutOfMemoryError: Java heap space_java

ds上传过大资源时，会一直卡在100%，后台的dolphinscheduler-api.log出现以下日志

Caused by: org.springframework.web.multipart.MultipartException: Failed to parse multipart servlet request; nested exception is `java.lang.OutOfMemoryError: Java heap space`

解决办法更改bin/dolphinscheduler-daemon.sh的api-server项内存大小参数建议其他也调大点，下面是我的，自己根据集群，酌情调整
