The webhook alert should contain a short helpful message explaining why an error is caused by the destination setup. In other snowplow loaders we get the message simply by serializing the Exception. But in Lake Loader I found the exception messages to be very messy.
In a related problem, for Hudi setup errors I needed to traverse the Exception's getCause in order to check if it was a setup error.
This PR takes more explicit control of setting short friendly error messages, and traversing the getCause to get all relevant messages.
E.g. an alert message before this change:
Failed to create events table: s3a://<REDACTED/events/_delta_log: org.apache.hadoop.fs.s3a.auth.NoAuthWithAWSException: No AWS Credentials provided by V1ToV2AwsCredentialProviderAdapter : software.amazon.awssdk.services.sts.model.StsException: User: arn:aws:iam:::user/ is not authorized to perform: sts:AssumeRole on resource: arn:aws:iam:::role/ (Service: Sts, Status Code: 403, Request ID: 00000000-0000-0000-0000-000000000000)
The corresponding alert after this change:
Failed to create events table: s3a://<REDACTED/events/_delta_log: Failed to initialize AWS access credentials: Missing permissions to assume the AWS IAM role
Other small changes I snuck into this commit:
Added specific webhook alerts for Hudi.
Removed the AssumedRoleCredentialsProvider for aws sdk v1. This is no longer needed now that Hadoop is fully using aws sdk v2.
Fixed minor bug with retrying creating a database in Hudi Writer
