[jira] [Commented] (HADOOP-14205) No FileSystem for scheme: adl
[ https://issues.apache.org/jira/browse/HADOOP-14205?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15932914#comment-15932914 ]
John Zhuge commented on HADOOP-14205:
-------------------------------------
The issues were caused by backporting HADOOP-13037 to branch-2 and earlier when HADOOP-12666 were not backported. Unfortunately some changes in HADOOP-12666 are needed.
