IMPALA-9997/IMPALA-9998: Upgrade compression libraries to latest versions
This updates several compression libraries to their latest versions:
- Bzip2 1.0.8
- LZ4 1.9.3
- Snappy 1.1.8
- Zlib 1.2.11
- ZStd 1.4.9
Several of these claim minor performance improvements.
Testing:
- Ran release exhaustive job and debug core job
- Ran TPC-H scale 42 with Parquet/Snappy and Parquet/ZSTD.
(ZSTD tests ran with default compression level.)
Parquet/Snappy was unchanged. Parquet/ZSTD improved:
+----------+------------------------+---------+------------+------------+----------------+
| Workload | File Format | Avg (s) | Delta(Avg) | GeoMean(s) |
Delta(GeoMean) |
+----------+------------------------+---------+------------+------------+----------------+
| TPCH(42) | parquet / zstd / block | 8.50 | -2.10% | 5.46 |
-2.63% |
