Get the path of the base, delta, or delete delta directory that will be the final destination of the files during compaction.

Parameters:

sd - storage descriptor of table or partition to compact

writeIds - list of valid writeids

conf - HiveConf

writingBase - if true, we are creating a base directory, otherwise a delta

createDeleteDelta - if true, the delta dir we are creating is a delete delta

bucket0 - whether to specify 0 as the bucketid

directory - AcidUtils.Directory - only required for minor compaction result (delta) dirs

Returns:

Path of new base/delta/delete delta directory
