flink sink oss problem

当我使用 https://github.com/apache/flink/pull/7798， 这个PR打pacth到flink 1.11.2，发现写flink通过Datastream写OSS功能并不可用。 报错信息如下： java.lang.RuntimeException: java.lang.RuntimeException: class org.apache.hadoop.security.JniBasedUnixGroupsMappingWithFallback not org.apache.flink.fs.shaded.hadoop3.org.apache.hadoop.security.GroupMappingServiceProvider at org.apache.flink.fs.shaded.hadoop3.org.apache.hadoop.conf.Configuration.getClass(Configuration.java:2624) at org.apache.flink.fs.shaded.hadoop3.org.apache.hadoop.security.Groups.
