…reCatalog Current `ParquetConversions` in `HiveMetastoreCatalog` will transformUp the given plan multiple times if there are many Metastore Parquet tables. Since the transformUp operation is recursive, it should be better to only perform it once. Author: Liang-Chi Hsieh <[email protected]> Closes #4651 from viirya/parquet_atonce and squashes the following commits: c1ed29d [Liang-Chi Hsieh] Fix bug. e0f919b [Liang-Chi Hsieh] Only transformUp the given plan once. (cherry picked from commit 4611de1) Signed-off-by: Michael Armbrust <[email protected]>
