- verified checksums and signature - built Flink from source release with Scala 2.12 - Executed some example jobs successfully - verified license and notice files
I found the following issues with some NOTICE files: * flink-connector-hive: org.apache.parquet:parquet-format:1.10.0 -> org.apache.parquet:parquet-format:2.4.0 * flink-connector-kinesis: com.amazonaws:aws-java-sdk-dynamodb:jar:1.11.754 -> com.amazonaws:aws-java-sdk-dynamodb:jar:1.11.603 com.amazonaws:aws-java-sdk-s3:jar:1.11.754 -> com.amazonaws:aws-java-sdk-s3:jar:1.11.603 com.amazonaws:aws-java-sdk-kms:jar:1.11.754 -> com.amazonaws:aws-java-sdk-kms:jar:1.11.603 * flink-sql-parquet: org.apache.commons:commons-compress:1.20 not used So these three modules report wrong versions for their dependencies in the NOTICE files. I would argue that this is not a big problem since the license did not change and we are not required to list ASL 2.0 dependencies. Hence, I would suggest to continue with the release voting. I will open a PR to fix these problems soon. Given that this is not a problem and that we don't find a problem in the network stack, +1 for this release candidate.
