Reading Hbase data directly from S3 after migrating Hbase to S3 without EMR

Hi bnaha,

Please go through the below steps I hope it will helps to resolve your issue

Approach 1: Direct S3 Access with Hadoop APIs

If you want to read the HBase data directly from S3 without using Glue and Athena:

1. Move HBase Files to S3: Use AWS DataSync or another method to move your HBase files to S3.

Document Link: https://aws.amazon.com/blogs/storage/using-aws-datasync-to-move-data-from-hadoop-to-amazon-s3/

2. Hadoop APIs: Use Hadoop APIs to read the HBase data directly from S3.

You can integrate the Hadoop APIs into your Spring Boot microservices to access the data.

Example:

Configuration conf = new Configuration();
conf.set("fs.s3a.access.key", "<YOUR_ACCESS_KEY>");
conf.set("fs.s3a.secret.key", "<YOUR_SECRET_KEY>");
conf.set("fs.s3a.endpoint", "s3.amazonaws.com");

FileSystem fs = FileSystem.get(URI.create("s3a://your-bucket-name"), conf);
Path path = new Path("s3a://your-bucket-name/path-to-hbase-files");
FSDataInputStream inputStream = fs.open(path);

// Process the input stream to read the HBase data

3. Spring Boot Microservices: Deploy your Spring Boot microservices in Fargate with the necessary configuration to read data from S3 using Hadoop APIs.

Approach 2: Using AWS SDK for S3

1. Move HBase Files to S3: Use AWS DataSync to move your HBase files to S3.

2. AWS SDK for Java: Use the AWS SDK for Java to directly read the data from S3 in your Spring Boot microservices.

Example:

AmazonS3 s3Client = AmazonS3ClientBuilder.standard()
                    .withRegion(Regions.DEFAULT_REGION)
                    .build();
                    
S3Object s3object = s3Client.getObject(new GetObjectRequest("your-bucket-name", "path-to-hbase-files"));
InputStream inputStream = s3object.getObjectContent();

// Process the input stream to read the HBase data

3. Spring Boot Microservices: Deploy your Spring Boot microservices in Fargate with the necessary configuration to read data from S3 using the AWS SDK.

Considerations

Performance: Evaluate the performance of reading large HBase files directly from S3. Depending on your data size and access patterns, Glue and Athena might offer optimizations.

Security: Ensure that your S3 bucket and data access are properly secured with IAM roles and policies.

Cost: Compare the cost implications of using Glue and Athena versus direct S3 access.
