Introduction

S3 Batch Operations process large numbers of objects in a single job. When a job fails, operations like copying objects, restoring from Glacier, or applying ACLs don't complete, leaving your data migration or lifecycle tasks incomplete.

Symptoms

Job failed:

```bash $ aws s3control describe-job \ --account-id 123456789 \ --job-id job-abc123

{ "Job": { "Status": "Failed", "FailureReasons": [ { "FailureCode": "InvalidManifest", "FailureReason": "Manifest file not found or invalid format" } ] } } ```

Task failures:

```bash $ aws s3control describe-job \ --account-id 123456789 \ --job-id job-abc123 \ --query 'Job.{Total:ProgressSummary.TotalNumberOfTasks,Failed:ProgressSummary.NumberOfTasksFailed}'

# Many tasks failing ```

Access denied errors:

bash
"FailureCode": "AccessDenied",
"FailureReason": "User is not authorized to perform the operation"

Common Causes

  1. 1.Invalid manifest format - CSV or inventory report incorrectly formatted
  2. 2.Manifest file inaccessible - Wrong bucket permissions or missing file
  3. 3.IAM role missing permissions - Job role can't access source/destination
  4. 4.Operation not supported - Mismatch between operation and object type
  5. 5.Job timeout - Job exceeded maximum duration
  6. 6.Bucket versioning issues - Version ID issues in manifest
  7. 7.KMS key access - Encrypted objects without key access

Step-by-Step Fix

  1. 1.Check logs for specific error messages
  2. 2.Verify configuration settings
  3. 3.Test network connectivity
  4. 4.Review recent changes
  5. 5.Apply corrective action
  6. 6.Verify the fix

Step 1: Check Job Status and Failure Reason

```bash # Get detailed job status aws s3control describe-job \ --account-id 123456789 \ --job-id job-abc123

# Key fields: # - Status: Failed, Completed, Active, etc. # - FailureReasons: Specific error codes # - ProgressSummary: Task counts

# Common failure codes: # - InvalidManifest: Manifest format or location issue # - AccessDenied: IAM permissions # - InvalidRequest: Configuration error # - InternalError: AWS-side issue ```

Step 2: Verify Manifest Format

```bash # Check manifest file location aws s3api head-object --bucket manifest-bucket --key manifest.csv

# For CSV manifest, format must be: # Bucket, Key [, VersionId] my-bucket,object1.jpg my-bucket,object2.pdf my-bucket,important.doc,VERSION_ID

# Check manifest content aws s3 cp s3://manifest-bucket/manifest.csv - | head -10

# For inventory report, must be valid S3 Inventory format # Check inventory configuration aws s3api get-bucket-inventory-configuration \ --bucket my-bucket \ --id daily-inventory ```

Step 3: Check IAM Role Permissions

```bash # Get job role ARN aws s3control describe-job \ --account-id 123456789 \ --job-id job-abc123 \ --query 'Job.RoleArn'

# Check role permissions aws iam get-role-policy --role-name S3BatchJobRole --policy-name S3BatchPolicy

# Required permissions for copy operation: { "Effect": "Allow", "Action": [ "s3:GetObject", "s3:GetObjectVersion", "s3:PutObject", "s3:ListBucket" ], "Resource": [ "arn:aws:s3:::source-bucket", "arn:aws:s3:::source-bucket/*", "arn:aws:s3:::dest-bucket", "arn:aws:s3:::dest-bucket/*" ] }

# Also need trust policy for batch operations: { "Version": "2012-10-17", "Statement": [{ "Effect": "Allow", "Principal": {"Service": "batchoperations.s3.amazonaws.com"}, "Action": "sts:AssumeRole" }] } ```

Step 4: Check Manifest Bucket Permissions

```bash # Job must be able to read manifest aws s3api get-object-acl --bucket manifest-bucket --key manifest.csv

# Verify bucket policy allows batch operations aws s3api get-bucket-policy --bucket manifest-bucket

# Add policy if needed aws s3api put-bucket-policy --bucket manifest-bucket --policy '{ "Version": "2012-10-17", "Statement": [{ "Effect": "Allow", "Principal": {"Service": "batchoperations.s3.amazonaws.com"}, "Action": ["s3:GetObject", "s3:GetObjectVersion"], "Resource": "arn:aws:s3:::manifest-bucket/manifest.csv" }] }' ```

Step 5: Review Job Report

```bash # Get completion report aws s3control describe-job \ --account-id 123456789 \ --job-id job-abc123 \ --query 'Job.JobReport'

# Report contains: # - Bucket: Where report is stored # - Prefix: Report file prefix # - Format: Report_CSV_20180220

# Download and examine report aws s3 cp s3://report-bucket/reports/job-abc123/report.csv - | head -20

# Report shows: Key, VersionId, ErrorCode, HTTPStatusCode ```

Step 6: Verify Operation Configuration

```bash # Get operation details aws s3control describe-job \ --account-id 123456789 \ --job-id job-abc123 \ --query 'Job.Operation'

# Operations: # - LambdaInvoke: Call Lambda function # - S3PutObjectCopy: Copy objects # - S3PutObjectAcl: Set ACLs # - S3PutObjectTagging: Set tags # - S3DeleteObjectTagging: Remove tags # - S3InitiateRestoreObject: Restore from Glacier # - S3PutObjectLegalHold: Set legal hold # - S3PutObjectRetention: Set retention

# Verify operation matches what you want ```

Step 7: Check for Version-Specific Issues

```bash # If source bucket has versioning, manifest may need version IDs aws s3api get-bucket-versioning --bucket source-bucket

# If Enabled, objects have version IDs # Manifest should include version ID column

# List object versions aws s3api list-object-versions --bucket source-bucket --prefix "path/" \ --query 'Versions[*].[Key,VersionId]' --output csv ```

Step 8: Test with Smaller Manifest

```bash # Create small test manifest cat > test-manifest.csv << EOF Bucket,Key my-bucket,test-object-1.txt my-bucket,test-object-2.txt EOF

aws s3 cp test-manifest.csv s3://manifest-bucket/test-manifest.csv

# Create test job aws s3control create-job \ --account-id 123456789 \ --manifest '{"Spec":{"Format":"S3BatchOperations_CSV_20180820","Fields":["Bucket","Key"]},"Location":{"ObjectArn":"arn:aws:s3:::manifest-bucket/test-manifest.csv","ETag":"ETAG"}}' \ --operation '{"S3PutObjectCopy":{"TargetResource":"arn:aws:s3:::dest-bucket"}}' \ --report '{"Bucket":"arn:aws:s3:::report-bucket","Prefix":"test-reports/","Format":"Report_CSV_20180220","Enabled":true}' \ --role-arn arn:aws:iam::123456789:role/S3BatchJobRole \ --priority 10 \ --confirmation-required ```

Step 9: Check for Timeout Issues

```bash # Jobs have maximum duration # Large operations may timeout

# Check job timing aws s3control describe-job \ --account-id 123456789 \ --job-id job-abc123 \ --query 'Job.{Created:CreationTime,Updated:LastUpdateTime,Status:Status}'

# For very large datasets: # 1. Split into multiple smaller jobs # 2. Use inventory reports with date ranges # 3. Increase priority for faster processing ```

Step 10: Handle Encryption Issues

```bash # Check if source objects are encrypted aws s3api head-object --bucket source-bucket --key object.txt \ --query 'ServerSideEncryption'

# If SSE-KMS, job role needs KMS permissions aws iam put-role-policy \ --role-name S3BatchJobRole \ --policy-name KMSAccess \ --policy-document '{ "Effect": "Allow", "Action": ["kms:Decrypt", "kms:GenerateDataKey"], "Resource": ["arn:aws:kms:region:account:key/key-id"] }' ```

Verification

```bash # After fixing, create new job or update failed job aws s3control update-job-priority \ --account-id 123456789 \ --job-id job-abc123 \ --priority 10

# Or create new job with fixed configuration

# Monitor job progress aws s3control describe-job \ --account-id 123456789 \ --job-id job-abc123 \ --query 'Job.{Status:Status,Progress:ProgressSummary}'

# Status should be "Completed" with NumberOfTasksFailed = 0 ```
