> Apache Kylin uses HBase's HFileOutputFormat2.java to configure the MR job. The original reporting is in KYLIN-2788[1]. After some investigation, we found this class always uses the default "FileOutputCommitter", see [2], regardless of the job's configuration; so it always writing to "_temporary" folder. Since AWS EMR configured to use DirectOutputCommitter for S3, then this problem occurs: Hadoop expects to see the file directly under output path, while the RecordWriter generates them in "_temporary" folder. This caused no data be loaded to HTable.
> Seems this problem exists in all versions so far.
