Since HiveIcebergInputformat doesn't implement any LLAP marker interfaces, cache affinity is never tried, and so any split containing ORC file parts may go to a random LLAP daemon, causing subpar hit ratio later. So we should: let HS2 know that cache affinity is required for this inputformat prevent Iceberg from grouping separate files together in one combined split in case of LLAP execution provide proper getPath() result for HiveIcebergSplit, so that HostAffinitySplitLocationProvider calculates different hashes for different files (right now getPath() returns table location only) -- This is an automated message from the Apache Git Service.
