## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import * as cdk from 'aws-cdk-lib';
import { aws_stepfunctions as stepfunctions } from 'aws-cdk-lib';
import { aws_stepfunctions_tasks as stepfunctions_tasks } from 'aws-cdk-lib';

declare const assign: any;
declare const resultSelector: any;
declare const taskRole: stepfunctions.TaskRole;
declare const timeout: stepfunctions.Timeout;
const emrModifyInstanceFleetByNameJsonPathProps: stepfunctions_tasks.EmrModifyInstanceFleetByNameJsonPathProps = {
  clusterId: 'clusterId',
  instanceFleetName: 'instanceFleetName',
  targetOnDemandCapacity: 123,
  targetSpotCapacity: 123,

  // the properties below are optional
  assign: {
    assignKey: assign,
  },
  comment: 'comment',
  credentials: {
    role: taskRole,
  },
  heartbeat: cdk.Duration.minutes(30),
  heartbeatTimeout: timeout,
  inputPath: 'inputPath',
  integrationPattern: stepfunctions.IntegrationPattern.REQUEST_RESPONSE,
  outputPath: 'outputPath',
  queryLanguage: stepfunctions.QueryLanguage.JSON_PATH,
  resultPath: 'resultPath',
  resultSelector: {
    resultSelectorKey: resultSelector,
  },
  stateName: 'stateName',
  taskTimeout: timeout,
  timeout: cdk.Duration.minutes(30),
};
```

## Properties

- `assign`: { [key: string]: any } = Not assign variables — Workflow variables to store in this step.

  Using workflow variables, you can store data in a step and retrieve that data in future steps.

- `clusterId`: string (required) — The ClusterId to update.

- `comment`: string = No comment — A comment describing this state.

- `credentials`: [Credentials](/cdk/api/v2/docs/aws-cdk-lib.aws_stepfunctions.Credentials.html) = None (Task is executed using the State Machine's execution role) — Credentials for an IAM Role that the State Machine assumes for executing the task.

  This enables cross-account resource invocations.

  **Default:** None (Task is executed using the State Machine's execution role)

- `heartbeat`: [Duration](/cdk/api/v2/docs/aws-cdk-lib.Duration.html) = None — use `heartbeatTimeout`

- `heartbeatTimeout`: [Timeout](/cdk/api/v2/docs/aws-cdk-lib.aws_stepfunctions.Timeout.html) = None — Timeout for the heartbeat.

  [disable-awslint:duration-prop-type] is needed because all props interface in
  aws-stepfunctions-tasks extend this interface

- `inputPath`: string = $ — JSONPath expression to select part of the state to be the input to this state.

  May also be the special value JsonPath.DISCARD, which will cause the effective
  input to be the empty object {}.

- `instanceFleetName`: string (required) — The InstanceFleetName to update.

- `integrationPattern`: [IntegrationPattern](/cdk/api/v2/docs/aws-cdk-lib.aws_stepfunctions.IntegrationPattern.html) = `IntegrationPattern.REQUEST_RESPONSE` for most tasks. `IntegrationPattern.RUN_JOB` for the following exceptions: `BatchSubmitJob`, `EmrAddStep`, `EmrCreateCluster`, `EmrTerminationCluster`, and `EmrContainersStartJobRun`. — AWS Step Functions integrates with services directly in the Amazon States Language.

  You can control these AWS services using service integration patterns.

  Depending on the AWS Service, the Service Integration Pattern availability will vary.

  **Default:** `IntegrationPattern.REQUEST_RESPONSE` for most tasks. `IntegrationPattern.RUN_JOB` for the following exceptions: `BatchSubmitJob`, `EmrAddStep`, `EmrCreateCluster`, `EmrTerminationCluster`, and `EmrContainersStartJobRun`.

- `outputPath`: string = $ — JSONPath expression to select part of the state to be the output to this state.

  May also be the special value JsonPath.DISCARD, which will cause the effective
  output to be the empty object {}.

- `queryLanguage`: [QueryLanguage](/cdk/api/v2/docs/aws-cdk-lib.aws_stepfunctions.QueryLanguage.html) = JSONPath — The name of the query language used by the state.

  If the state does not contain a `queryLanguage` field,
  then it will use the query language specified in the top-level `queryLanguage` field.

- `resultPath`: string = $ — JSONPath expression to indicate where to inject the state's output.

  May also be the special value JsonPath.DISCARD, which will cause the state's
  input to become its output.

- `resultSelector`: { [key: string]: any } = None — The JSON that will replace the state's raw result and become the effective result before ResultPath is applied.

  You can use ResultSelector to create a payload with values that are static
  or selected from the state's raw result.

- `stateName`: string = The construct ID will be used as state name — Optional name for this state.

  **Default:** The construct ID will be used as state name

- `targetOnDemandCapacity`: number (required) = None — The target capacity of On-Demand units for the instance fleet.

- `targetSpotCapacity`: number (required) = None — The target capacity of Spot units for the instance fleet.

- `taskTimeout`: [Timeout](/cdk/api/v2/docs/aws-cdk-lib.aws_stepfunctions.Timeout.html) = None — Timeout for the task.

  [disable-awslint:duration-prop-type] is needed because all props interface in
  aws-stepfunctions-tasks extend this interface

- `timeout`: [Duration](/cdk/api/v2/docs/aws-cdk-lib.Duration.html) = None — use `taskTimeout`
