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
