描述
Test runs of parquet-hadoop with `-Dhadoop.version=3.4.0` fail because there's a logback jar on the classpath, which screws things up (mostly seemingly because it suddenly logs at debug)
HADOOP-19084 should have fixed this, as it explicitly excludes the export. clearly not. created HADOOP-19153 as a followup.
For now, all parquet needs is to exclude logback as a hadoop-common dependency. I'll be extra cautious and get rid of all log dependencies.

调研方向
先从 parquet-hadoop 的测试设置和依赖配置入手,然后使用 -Dhadoop.version=3.4.0 运行测试,以复现 classpath 问题。检查 Hadoop 依赖不再将不需要的 logging jar 带入测试 classpath,并确认测试通过;HADOOP-19153 和 pull request #1321 提供了有关已在进行的工作的背景信息。
