             Summary: HdfsFileStatus incompatibility when used with Hadoop 3.1.x
                 Key: HBASE-22394
                 URL: https://issues.apache.org/jira/browse/HBASE-22394
             Project: HBase
          Issue Type: Bug
          Components: regionserver
    Affects Versions: 2.1.4
            Reporter: Raymond Lau


Hbase 2.1.4 works fine with Hadoop 3.0.3 but when I attempted to upgrade to 
Hadoop 3.1.2, I get the following error in the region server:

Hadoop 3.1.1+ is listed as compatible with Hbase 2.1.x at 
[https://hbase.apache.org/book.html#basic.prerequisites].
