Gopal V commented on HIVE-22045:
--------------------------------
The FileSinkDesc:isCTas* method needs more docs in the declaration.
And I'm trying to figure out the actual impact of
{code}
- boolean isBlobStorage = BlobStorageUtils.isBlobStorageFileSystem(hconf, fs);
{code}
Is that going to be another perf regression?

> Better fix for HIVE-21711 is to specialize the handling for CTAS/Create MV
> statements to avoid intermittent rename operation but keep INSERT etc
> statements do intermittent rename since otherwise final move by file
> operation is significantly slow for such statements.
