xiaohang.li commented on FLINK-30001:
-------------------------------------
经查询，
默认情况下 flink 中的 org.apache.flink.table.planner.loader.PlannerModule 模块使用 /tmp
目录来作为临时的工作路径，因此会尝试调用 jave 的 java.nio.file.Files 类来创建这个目录，但是如果 /tmp 目录是一个指向
/mnt/tmp 的符号软链接，这种情况 java.nio.file.Files
类无法处理，从而导致出现报错。需要在sql-client.sh添加临时路径的配置：
export JVM_ARGS="-Djava.io.tmpdir=/mnt/tmp
> sql-client.sh start failed
