描述
remove the deprecated PathGlobPattern class and its uses from parquet-thrift
The return types from the hadoop GlobPattern code changed in HADOOP-12436; in the class as is will not compile against hadoop 3.x
Parquet releases compiled against hadoop 2.x will not be able to instantiate these classes on a hadoop 3 release, because things will not link.
Nobody appears to have complained about the linkage problem to the extent of filing a JIRA.

调研方向
首先在 parquet-thrift 下定位 PathGlobPattern、DeprecatedFieldProjectionFilter 及其使用位置,然后检查 Hadoop GlobPattern API 和 Hadoop 3.2 依赖项变更。移除已弃用的类和引用,并验证 parquet-thrift 能够针对 Hadoop 3.2 或更高版本进行编译。
