[jira] [Reopened] (HDFS-15396) Fix
TestViewFileSystemOverloadSchemeHdfsFileSystemContract#testListStatusRootDir
[ https://issues.apache.org/jira/browse/HDFS-15396?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Uma Maheswara Rao G reopened HDFS-15396:
----------------------------------------
I have just noticed you did changes only in ViewFileSystem.java, but we should do same change in ViewFs.java also. Probably let's this JIRA stick to test passing. Reminder of change I will keep in HADOOP-17060. Or you want to revert and add that also? Let me know I will keep changes accordingly. ( Note: HADOOP-17060 has changes in both ViewFileSystem.java and ViewFs.java).

> The reason for failure being, the mount destination for /user and /append in the test is just the URI, with no further path.
> Thus while listing, in order to fetch the permissions, the destination URI is used to get the path, which resolves being empty. Hence the failure
