wangyum opened a new pull request #24346: [SPARK-27176][FOLLOW-UP][SQL] Upgrade Hive parquet to 1.10.1
URL: https://github.com/apache/spark/pull/24346
## What changes were proposed in this pull request?
When we compile and test Hadoop 3.2, we will hint the following two issues:
1. JobSummaryLevel is not a member of object org.apache.parquet.hadoop.ParquetOutputFormat. Fixed by [PARQUET-381](https://issues.apache.org/jira/browse/PARQUET-381)(Parquet 1.9.0)
2. java.lang.NoSuchFieldError: BROTLI
at org.apache.parquet.hadoop.metadata.CompressionCodecName.<clinit>(CompressionCodecName.java:31). Fixed by [PARQUET-1143](https://issues.apache.org/jira/browse/PARQUET-1143)(Parquet 1.10.0)
The reason is that the `parquet-hadoop-bundle-1.8.1.jar` conflicts with Parquet 1.10.1.
I think it would be safe to upgrade Hive's parquet to 1.10.1 to workaround this issue.
This is what Hive did when upgrading Parquet 1.8.1 to 1.10.0: [HIVE-17000](https://issues.apache.org/jira/browse/HIVE-17000) and [HIVE-19464](https://issues.apache.org/jira/browse/HIVE-19464). We can see that all changes are related to vectors, and vectors are disabled by default: see [HIVE-14826](https://issues.apache.org/jira/browse/HIVE-14826) and [HiveConf.java#L2723](https://github.com/apache/hive/blob/rel/release-2.3.4/common/src/java/org/apache/hadoop/hive/conf/HiveConf.java#L2723).
## How was this patch tested?
1. manual tests
2. [upgrade Hive Parquet to 1.10.1 annd run Hadoop 3.2 test on jenkins](https://github.com/apache/spark/pull/24044#commits-pushed-0c3f962)
