In HFileOutputFormat2.createRecordWriter we cast the passed in > committer as a FileOutputCommitter. This causes a class cast exception when > the s3 magic committer is enabled: > > {code:java} > Error: java.lang.ClassCastException: class > org.apache.hadoop.fs.s3a.commit.magic.MagicS3GuardCommitter cannot be cast to > class org.apache.hadoop.mapreduce.lib.output.FileOutputCommitter {code} > > We can cast to PathOutputCommitter instead, but its only available in > hadoop3+. So we will need to use reflection to work around this in branch-2. -- This message was sent by Atlassian Jira (v8.20.10#820010)
