@aws-sdk/client-emr

Description

AWS SDK for JavaScript EMR Client for Node.js, Browser and React Native.

Amazon EMR is a web service that makes it easier to process large amounts of data efficiently. Amazon EMR uses Hadoop processing combined with several Amazon Web Services services to do tasks such as web indexing, data mining, log file analysis, machine learning, scientific simulation, and data warehouse management.

Installing

To install this package, simply type add or install @aws-sdk/client-emr using your favorite package manager:

  • npm install @aws-sdk/client-emr
  • yarn add @aws-sdk/client-emr
  • pnpm add @aws-sdk/client-emr

Getting Started

Import

The AWS SDK is modulized by clients and commands. To send a request, you only need to import the EMRClient and the commands you need, for example ListStudiosCommand:

// ES5 example
const { EMRClient, ListStudiosCommand } = require("@aws-sdk/client-emr");
// ES6+ example
import { EMRClient, ListStudiosCommand } from "@aws-sdk/client-emr";

Usage

To send a request, you:

  • Initiate client with configuration (e.g. credentials, region).
  • Initiate command with input parameters.
  • Call send operation on client with command object as input.
  • If you are using a custom http handler, you may call destroy() to close open connections.
// a client can be shared by different commands.
const client = new EMRClient({ region: "REGION" });

const params = {
  /** input parameters */
};
const command = new ListStudiosCommand(params);
Async/await

We recommend using await operator to wait for the promise returned by send operation as follows:

// async/await.
try {
  const data = await client.send(command);
  // process data.
} catch (error) {
  // error handling.
} finally {
  // finally.
}

Async-await is clean, concise, intuitive, easy to debug and has better error handling as compared to using Promise chains or callbacks.

Promises

You can also use Promise chaining to execute send operation.

client.send(command).then(
  (data) => {
    // process data.
  },
  (error) => {
    // error handling.
  }
);

Promises can also be called using .catch() and .finally() as follows:

client
  .send(command)
  .then((data) => {
    // process data.
  })
  .catch((error) => {
    // error handling.
  })
  .finally(() => {
    // finally.
  });
Callbacks

We do not recommend using callbacks because of callback hell, but they are supported by the send operation.

// callbacks.
client.send(command, (err, data) => {
  // process err and data.
});
v2 compatible style

The client can also send requests using v2 compatible style. However, it results in a bigger bundle size and may be dropped in next major version. More details in the blog post on modular packages in AWS SDK for JavaScript

import * as AWS from "@aws-sdk/client-emr";
const client = new AWS.EMR({ region: "REGION" });

// async/await.
try {
  const data = await client.listStudios(params);
  // process data.
} catch (error) {
  // error handling.
}

// Promises.
client
  .listStudios(params)
  .then((data) => {
    // process data.
  })
  .catch((error) => {
    // error handling.
  });

// callbacks.
client.listStudios(params, (err, data) => {
  // process err and data.
});

Troubleshooting

When the service returns an exception, the error will include the exception information, as well as response metadata (e.g. request id).

try {
  const data = await client.send(command);
  // process data.
} catch (error) {
  const { requestId, cfId, extendedRequestId } = error.$metadata;
  console.log({ requestId, cfId, extendedRequestId });
  /**
   * The keys within exceptions are also parsed.
   * You can access them by specifying exception names:
   * if (error.name === 'SomeServiceException') {
   *     const value = error.specialKeyInException;
   * }
   */
}
