[jira] [Commented] (HBASE-22394) HdfsFileStatus incompatibility
when used with Hadoop 3.1.x
[ https://issues.apache.org/jira/browse/HBASE-22394?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16839906#comment-16839906 ]
Duo Zhang commented on HBASE-22394:
-----------------------------------
I think you have to build from source by changing the hadoop-three.version to 3.1.2 and try again. Drop-in replacement sometimes does not work.
