@Michael, I answered in Jira and could repeat here. I think that my problem is unrelated to Hive, because I'm using read.parquet method. I also attached some VisualVM snapshots to SPARK-16321 (I think I should merge both issues) And code profiling suggest bottleneck when reading parquet file.
I wonder if there are any other benchmarks related to parquet performance. Regards, -- Maciek Bryński
