### Steps to reproduce

1. make any parent path of ENGINECONN_ROOT_DIR to no execute permission for **others**. For example, ENGINECONN_ROOT_DIR is **/home/hadoop/linkis/tmp**, and **/home/hadoop** permission is **rwx------** (In fact, default permission of user home is exactly this in centos)
2. use non-hadoop user as executeUser to submit job, such as hadoop2
3. see error log that hadoop2 has no permission to **/home/hadoop/linkis/tmp/xxxxxx/engineConnExec.sh**

### Expected behavior

With no execute permission of any parent path of a file, user cannot access that file. ECM should change all parent path of ENGINECONN_ROOT_DIR to have execute permission for **others**, better to be **rwxr-xr-x**

### Your environment

- Linkis version used: 1.1.2
- Environment name and version:
- cdh-5.14.2
- hdp-3.1.5
- hive-2.1.1
- spark-3.2.1
- scala-2.12.2
- jdk 1.8.0_121
- ....

### Are you willing to submit a PR?

- [x] Yes I am willing to submit a PR!

Start with ECM's handling of ENGINECONN_ROOT_DIR and creation or execution of engineConnExec.sh. Reproduce the submission as a non-hadoop executeUser when a parent directory lacks execute permission, then trace how parent-directory permissions are handled. Done means the generated script is accessible to the executeUser without breaking the reported environment.
