Receives a bootstrap action as loaded from the configuration file and

Files will be uploaded to S3 if needed.
YAML OPTIONS:
The action can be defined using one of "script", "dir", "s3" or "command".
If an action has more than one defined only the first one will matter.
name: string
Bootstrap action name. If not given, the file name will be used.
script: string
Path to local file that will be uploaded to S3 and passed on to boto3.
Arguments can be passed on inline or through the args key. Inline
arguments will be inserted before the 'args' ones.
dir: string
Path to a local directory that contains scripts to be executed as
bootstrap actions. For each file the function will call itself with
the 'dir' key replaced with a 'script' key. The files will be ordered
alphabetically, case insensitive. Arguments will be passed to every
script, if defined.
s3: string
Path to script on S3. 's3://' will be added if it's not there.
command: string
Path to a file that already exists on the EMR host.
Args:
bootstrap_action (list): as read from the config file
s3bucket (string): if a script/dir was passed, it will be uploaded to
this bucket, unless overwritten by an action option
s3prefix (string): prefix to be used for the action name if it has to
be uploaded to S3. Can be overwritten for each action

"""Converts step to boto3 structure.
Converts an EMR 'step' from the simplified yaml format to the syntax
needed to pass a step to boto3 EMR client methods like run_job_flow() or
add_job_flow_steps(). EMR 4.x only.
YAML structure:
The step to be executed will be defined using one of 'exec', 'script',
'dir', 's3' or 'command'. For each step, only one of these should be
defined. The first one encountered will determine the actions taken, the
rest will be ignored.
name: string, required
name of the step.
on_failure: string, case insensitive, default is "TERMINATE_CLUSTER"
what to do if the step fails.
valid values are (case insensitive):
- terminate | terminate_cluster | terminate_job_flow
- cancel | wait | cancel_and_wait
- continue
type: string, case insensitive, default is "CUSTOM_JAR"
what kind of step this is. it can be a custom jar to be executed as-is,
or it can be a script that will be passed to another application by
"command-runner.jar". valid values (at the end of 2015) are:
- custom_jar | custom | jar
- streaming | hadoop-streaming | hadoop_streaming
- hive | hive-script | hive_script
- pig
- impala
- spark
- shell - shell scripts are run using script-runner.jar
NOT ALL OF THEM ARE IMPLEMENTED
exec: string
URI to the script/jar to be executed. Will be passed to boto3 as-is.
script: string
Path to local file that will be uploaded to S3 and passed on to boto3.
Arguments can be passed inline or through the args key. Inline
arguments will be inserted before the 'args' ones.
dir: string
Path to a local directory that contains scripts to be executed as
steps. For each file the function will call itself with 'dir'
replaced with 'script'. The files will be ordered alphabetically,
case insensitive. Arguments will be passed to every script, if defined.
s3: string
Path to script on S3. 's3://' will be added if it's not there.
command: string
Path to a file that already exists on the EMR host. Arguments inline
or as 'args'
args: list
arguments to be passed to the step. depending on the step `type` the
list will be interpreted in different ways (or not)
main_class: string
the name of the main class in the specified Java file. if not
specified, the JAR file should specify a Main-Class in its manifest
file. will pe passed on as-is
properties: list
a list of Java properties that are set when the step runs. you can use
these properties to pass key value pairs to your main function. will be
passed on as-is
Args:
yaml_step (dict): the step as read from yaml file.
s3bucket (string): name of the bucket that steps will be upladed to
if they are local scripts
s3prefix (string): 'directory' in the bucket
session (session): an already defined session object for uploading
Returns:
a list element that can be added to the list of steps the cluster should
execute
