Hi all, I want to get some insights on how many users are still using Hadoop 2 vs how many users are using Hadoop 3. Flink currently requires a minimum version of Hadoop 2.10.2 for certain features, but also extensively uses Hadoop 3 (like for the file system implementations)
Hadoop 2 has a large number of direct and indirect vulnerabilities [1]. Most of them can only be resolved by dropping support for Hadoop 2 and upgrading to a Hadoop 3 version. This thread is primarily to get more insights if Hadoop 2 is still commonly used, or if we can actually discuss dropping support for Hadoop 2 in Flink. Best regards, Martijn [1] https://mvnrepository.com/artifact/org.apache.hadoop/hadoop-common/2.10.2
