Description

Hi 

I am new user for aurora. When I follow latest hello world doc (http://aurora.apache.org/documentation/latest/getting-started/tutorial/) to run first hello world aurora job, I meet below issues:

D0605 16:17:01.721896 8320 process.py:155] [process: 8320=hello_world]: Error trying to execute hello_world: [Errno 13] Permission denied: 

How to solve this issue?

 

The below is "thermos_runner.DEBUG" log in Mesos Agent:

The below is /etc/aurora/clusters.json:

[root@cloudpoc3 ~]# more /etc/aurora/clusters.json
[

{ "auth_mechanism": "UNAUTHENTICATED", "name": "devcluster", "scheduler_zk_path": "/aurora/scheduler", "slave_root": "/var/lib/mesos", "slave_run_directory": "latest", "zk": "127.0.0.1" }

]

+_*The below is hello_world.aurora file:*_+

pkg_path = '/opt/aurora_test/hello_world.py'

1. we use a trick here to make the configuration change with
2. the contents of the file, for simplicity. in a normal setting, packages would be
3. versioned, and the version number would be changed in the configuration.
   import hashlib
   with open(pkg_path, 'rb') as f:
   pkg_checksum = hashlib.md5(f.read()).hexdigest()

1. copy hello_world.py into the local sandbox
   install = Process(
   name = 'fetch_package',
   cmdline = 'cp %s . && echo %s && chmod +x hello_world.py' % (pkg_path, pkg_checksum))

1. run the script
2. cmdline = 'python -u hello_world.py'
   hello_world = Process(
   name = 'hello_world',
   cmdline = 'echo "---gang-hello aurora------";')

1. describe the task
   hello_world_task = SequentialTask(
   processes = [hello_world],
   resources = Resources(cpu = 2, ram = 4096*MB, disk=4096*MB))

jobs = [
Service(cluster = 'devcluster',
environment = 'devel',
role = 'www-data',
name = 'hello_world',
task = hello_world_task)
]

From Mesos WebUI, it seems normal:
