2017/11/29 - AWS Batch - 3 updated api methods
Changes Add support for Array Jobs which allow users to easily submit many copies of a job with a single API call. This change also enhances the job dependency model to support N_TO_N and sequential dependency chains. The ListJobs and DescribeJobs APIs now have the ability to list or describe the status of entire Array Jobs or individual elements within the array.

The Unix time stamp for when the attempt was started (when the attempt transitioned from the STARTING state to the RUNNING state).
stoppedAt (integer) --
The Unix time stamp for when the attempt was stopped (when the attempt transitioned from the RUNNING state to a terminal state, such as SUCCEEDED or FAILED ).

statusReason (string) --
A short, human-readable string to provide additional details about the current status of the job.

The retry strategy to use for this job if an attempt fails.
attempts (integer) --

If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data is not guaranteed to persist after the containers associated with it stop running.
sourcePath (string) --
The path on the host container instance that is presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If the host parameter contains a sourcePath file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the sourcePath value does not exist on the host container instance, the Docker daemon creates it. If the location does exist, the contents of the source path folder are exported.

client.list_jobs(
jobQueue='string',
arrayJobId='string',
jobStatus='SUBMITTED'|'PENDING'|'RUNNABLE'|'STARTING'|'RUNNING'|'SUCCEEDED'|'FAILED',
maxResults=123,
nextToken='string'
)
string
The name or full Amazon Resource Name (ARN) of the job queue with which to list jobs.
string
The job ID for an array job. Specifying an array job ID with this parameter lists all child jobs from within the specified array.
string
The job status with which to filter jobs in the specified queue. If you do not specify a status, only RUNNING jobs are returned.
integer
The maximum number of results returned by ListJobs in paginated output. When this parameter is used, ListJobs only returns maxResults results in a single page along with a nextToken response element. The remaining results of the initial request can be seen by sending another ListJobs request with the returned nextToken value. This value can be between 1 and 100. If this parameter is not used, then ListJobs returns up to 100 results and a nextToken value if applicable.
string
The nextToken value returned from a previous paginated ListJobs request where maxResults was used and the results exceeded the value of that parameter. Pagination continues from the end of the previous results that returned the nextToken value. This value is null when there are no more results to return.
Note
This token should be treated as an opaque identifier that is only used to retrieve the next items in a list and not for other programmatic purposes.
