Subject [jira] [Updated] (HADOOP-14745) s3a getFileStatus can't return expect result when existing a file and directory with the same name
Date Tue, 08 Aug 2017 09:34:00 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-14745?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Ewan Higgs updated HADOOP-14745:
--------------------------------
    Description: 
{code}
[**** hadoop-aws]# /root/hadoop/s3cmd/s3cmd ls s3://test-aws-s3a/user/root/
                       DIR   s3://test-aws-s3a/user/root/ccc/
2017-08-08 07:04         0   s3://test-aws-s3a/user/root/ccc
{code}
if we expect to ccc is a directory by code :
{code}
    Path test=new Path("ccc");
    fs.getFileStatus(test);
{code}
actually, it will tell us it is a file:
{code}
