Zoltan Haindrich commented on HIVE-17620:
-----------------------------------------
+1 think the new methods makes much more sense than the previous ones
the failure of
itests/hive-blobstore/src/test/results/clientpositive/write_final_output_blobstore.q.out
seems to be caused by the fix: the move operator's source is now a staging path
> Use the default MR scratch directory (HDFS) in the only case when
> hive.blobstore.optimizations.enabled=true AND isFinalJob=true

> Introduced in HIVE-15121. Context::getTempDirForPath tries to use temporary
> MR directory instead of blobstore directory in three cases:
> {code}
> if (!isFinalJob && BlobStorageUtils.areOptimizationsEnabled(conf)) {
> {code}
> while the only valid case for using a temporary MR dir is when optimization
> is enabled and the job is not final:
> {code}
> if (BlobStorageUtils.areOptimizationsEnabled(conf) && !isFinalJob) {
> {code}
