Change subject: IMPALA-8630: Include partition id when calculating consistent remote placement ...................................................................... IMPALA-8630: Include partition id when calculating consistent remote placement Consistent remote placement currently uses the relative filename within a partition for the consistent hash. If the relative filenames for different partitions have a simple naming scheme, then multiple partitions may have files of the same name. This is true for some tables written by Hive (e.g. in our minicluster the tpcds.store_sales has this problem). This can lead to unbalanced placement of remote ranges. This adds the partition_id in the hash, so files with the same name from different partitions will have different hashes.
