Description
AWS SDK for JavaScript EMRContainers Client for Node.js, Browser and React Native.
Amazon EMR on EKS provides a deployment option for Amazon EMR that allows
you to run open-source big data frameworks on Amazon Elastic Kubernetes Service (Amazon EKS).
With this deployment option, you can focus on running analytics workloads while Amazon EMR on EKS builds, configures, and manages containers for open-source applications.
For more information about Amazon EMR on EKS concepts and tasks, see What is
Amazon EMR on EKS.
Amazon EMR containers is the API name for Amazon EMR on EKS. The emr-containers
prefix is used in the following
scenarios:
-
It is the prefix in the CLI commands for Amazon EMR on EKS. For example,
aws emr-containers start-job-run
.
-
It is the prefix before IAM policy actions for Amazon EMR on EKS. For
example, "Action": [ "emr-containers:StartJobRun"]
. For more
information, see Policy actions for Amazon EMR on EKS.
-
It is the prefix used in Amazon EMR on EKS service endpoints. For example,
emr-containers.us-east-2.amazonaws.com
. For more information, see
Amazon EMR on EKSService Endpoints.
Installing
To install the this package, simply type add or install @aws-sdk/client-emr-containers
using your favorite package manager:
npm install @aws-sdk/client-emr-containers
yarn add @aws-sdk/client-emr-containers
pnpm add @aws-sdk/client-emr-containers
Getting Started
Import
The AWS SDK is modulized by clients and commands.
To send a request, you only need to import the EMRContainersClient
and
the commands you need, for example ListJobRunsCommand
:
const { EMRContainersClient, ListJobRunsCommand } = require("@aws-sdk/client-emr-containers");
import { EMRContainersClient, ListJobRunsCommand } from "@aws-sdk/client-emr-containers";
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.
const client = new EMRContainersClient({ region: "REGION" });
const params = {
};
const command = new ListJobRunsCommand(params);
Async/await
We recommend using await
operator to wait for the promise returned by send operation as follows:
try {
const data = await client.send(command);
} catch (error) {
} 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) => {
},
(error) => {
}
);
Promises can also be called using .catch()
and .finally()
as follows:
client
.send(command)
.then((data) => {
})
.catch((error) => {
})
.finally(() => {
});
Callbacks
We do not recommend using callbacks because of callback hell,
but they are supported by the send operation.
client.send(command, (err, 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-containers";
const client = new AWS.EMRContainers({ region: "REGION" });
try {
const data = await client.listJobRuns(params);
} catch (error) {
}
client
.listJobRuns(params)
.then((data) => {
})
.catch((error) => {
});
client.listJobRuns(params, (err, 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);
} catch (error) {
const { requestId, cfId, extendedRequestId } = error.$metadata;
console.log({ requestId, cfId, extendedRequestId });
}
