Hello! I'm trying to test out Minio as state storage backend using docker-compose on my local machine but keep running into errors that seem strange to me. Any help would be much appreciated :)
The problem: With the following environment: environment: - | FLINK_PROPERTIES= jobmanager.rpc.address: flink-jobmanager parallelism.default: 2 s3.access-key: <key> s3.secret-key: <key> s3.path.style.access: true And the following State Backend (with flink-jdbc-test_graph-minio_1 being the container serving minio): val bsEnv = StreamExecutionEnvironment.getExecutionEnvironment bsEnv.setStateBackend( new RocksDBStateBackend( "s3://flink-jdbc-test_graph-minio_1/data/checkpoints:9000", true ) ) And submitting the flink job and saving from another docker container like so: flink run -m flink-jdbc-test_flink-jobmanager_1:8081 -c <Job Class Name> <built code>.jar flink savepoint -m flink-jdbc-test_flink-jobmanager_1:8081 <Job ID> s3://flink-jdbc-test_graph-minio_1:9000/data/savepoints I end up with the following error: Caused by: com.facebook.presto.hive.s3.PrestoS3FileSystem$UnrecoverableS3OperationException: com.amazonaws.services.s3.model.AmazonS3Exception: Bad Request (Service: Amazon S3; Status Code: 400; Error Code: 400 Bad Request; Request ID: A7E3BB7EEFB524FD; S3 Extended Request ID: cJOtc6E3Kb+U5hgbkA+09Dd/ouDHBGL2ftb1pGHpIwFgd6tE461nkaDtjOj40zbWEpFAcMOEmbY=), S3 Extended Request ID: cJOtc6E3Kb+U5hgbkA+09Dd/ouDHBGL2ftb1pGHpIwFgd6tE461nkaDtjOj40zbWEpFAcMOEmbY= (Path: s3://flink-jdbc-test_graph-minio_1:9000/data/savepoints/savepoint-5c4090-5f90e0cdc603/_metadata) at com.facebook.presto.hive.s3.PrestoS3FileSystem.lambda$getS3ObjectMetadata$2(PrestoS3FileSystem.java:573) at com.facebook.presto.hive.RetryDriver.run(RetryDriver.java:138) at com.facebook.presto.hive.s3.PrestoS3FileSystem.getS3ObjectMetadata(PrestoS3FileSystem.java:560) at com.facebook.presto.hive.s3.PrestoS3FileSystem.getFileStatus(PrestoS3FileSystem.java:311) at org.apache.hadoop.fs.FileSystem.exists(FileSystem.java:1398) at com.facebook.presto.hive.s3.PrestoS3FileSystem.create(PrestoS3FileSystem.java:356) at org.apache.hadoop.fs.FileSystem.create(FileSystem.java:906) at org.apache.hadoop.fs.FileSystem.create(FileSystem.java:887) at org.apache.hadoop.fs.FileSystem.create(FileSystem.java:784) at org.apache.flink.fs.s3presto.common.HadoopFileSystem.create(HadoopFileSystem.java:141) at org.apache.flink.fs.s3presto.common.HadoopFileSystem.create(HadoopFileSystem.java:37) at org.apache.flink.core.fs.PluginFileSystemFactory$ClassLoaderFixingFileSystem.create(PluginFileSystemFactory.java:169) at org.apache.flink.runtime.state.filesystem.FsCheckpointMetadataOutputStream.<init>(FsCheckpointMetadataOutputStream.java:65) at org.apache.flink.runtime.state.filesystem.FsCheckpointStorageLocation.createMetadataOutputStream(FsCheckpointStorageLocation.java:109) at org.apache.flink.runtime.checkpoint.PendingCheckpoint.finalizeCheckpoint(PendingCheckpoint.java:306) ... 10 more Caused by: com.amazonaws.services.s3.model.AmazonS3Exception: Bad Request (Service: Amazon S3; Status Code: 400; Error Code: 400 Bad Request; Request ID: A7E3BB7EEFB524FD; S3 Extended Request ID: cJOtc6E3Kb+U5hgbkA+09Dd/ouDHBGL2ftb1pGHpIwFgd6tE461nkaDtjOj40zbWEpFAcMOEmbY=) at com.amazonaws.http.AmazonHttpClient$RequestExecutor.handleErrorResponse(AmazonHttpClient.java:1799) If I add to the environment to include: ... s3.endpoint: s3://flink-jdbc-test_graph-minio_1:9000 ...
