Xiang Li updated HADOOP-19239:
------------------------------
Description:
We have an online service which uses Hadoop FileSystem to load files from
Clould storage.
The currently cache in FileSystem is a HashMap, and its key honors scheme,
authority (like
[user@host:port|https://en.wikipedia.org/wiki/Uniform_Resource_Identifier#Syntax]),
ugi and a unique long for its [hash
code|https://github.com/apache/hadoop/blob/4525c7e35ea22d7a6350b8af10eb8d2ff68376e7/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/fs/FileSystem.java#L3891C1-L3894C8].
