当我尝试使用Apache Beam和Apache Flink使用Docker容器（集群模式）部署测试项目时，出现此错误：
org.apache.beam.sdk.util.UserCodeException: java.io.IOException: Unable to create parent directories for '/home/beam-test/.temp-beam-2018-06-15_12-57-41-0/549f66ca-c1f8-42d7-91e8-dec27f0689b7'

我尝试安装一个docker卷来放置输入和输出文件，但是在尝试创建临时目录的过程中它失败了。
我检查了所有者和组对docker卷的访问权限并且没关系（手动我可以创建和删除里面的文件和目录）。
你知道为什么会发生这种情况吗？
JDK和Flink Docker Image会出现问题吗？
Docker Image：Flink（https://hub.docker.com/r/library/flink/） JDK安装： Openjdk版“1.8.0_171” OpenJDK运行时环境（build 1.8.0_171-8u171-b11-1~deb9u1-b11） OpenJDK 64位服务器VM（版本25.171-b11，混合模式）
