-------------------------------
Summary: Support router path or view fs path in Hive table location
Key: HIVE-24742
URL: https://issues.apache.org/jira/browse/HIVE-24742
Project: Hive
Issue Type: Improvement
Components: Hive
Affects Versions: 3.1.2
Reporter: Aihua Xu
Assignee: Aihua Xu
In
[FileUtils.java|https://github.com/apache/hive/blob/master/common/src/java/org/apache/hadoop/hive/common/FileUtils.java#L747],
equalsFileSystem function checks the base URL to determine if source and
destination are on the same cluster and decides copy or move the data. That
will not work for viewfs or router base file system since viewfs://ns-default/a
and viewfs://ns-default/b may be on different physical clusters.
FileSystem in HDFS supports resolvePath() function to resolve to the physical
path. We can support viewfs and router through such function.
