Fix: list_applications throwing error

[brettsimons]

list_applications was previously throwing this error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "...\aztk\spark\client\base\operations.py", line 85, in list_applications
    return list_applications.list_applications(self, id)
  File "...\aztk\spark\client\base\helpers\list_applications.py", line 21, in list_applications
    return models.Application(_list_applications(core_operations, id))
  File "...\aztk\spark\client\base\helpers\list_applications.py", line 11, in _list_applications
    scheduling_target = core_operations.get_cluster_configuration(id).scheduling_target
AttributeError: 'ClusterOperations' object has no attribute 'get_cluster_configuration'

It is now working and returns a list of tasks.

Here is a workaround for the current release: Client.cluster._core_cluster_operations.list_batch_tasks(cluster_id)

Thanks for reporting this, can you confirm, were you experiencing this issue on the latest released version (0.10.2)?

[brettsimons]

Yes, I've only validated that this is an issue in 0.10.2. After looking a bit more at the source, I'll update the fix to return an array of aztk.spark.models.Application.

Looks great -- thanks for fixing!
