Jagadesh Kiran N created HDFS-9284:
--------------------------------------

             Summary: fsck command should not print exception trace when file not found 
                 Key: HDFS-9284
                 URL: https://issues.apache.org/jira/browse/HDFS-9284
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Jagadesh Kiran N
            Assignee: Jagadesh Kiran N


when file doesnt exist fsck throws exception 
{code}
./hdfs fsck /kiran
{code}

the following exception occurs 
{code}
WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using
builtin-java classes where applicable
FileSystem is inaccessible due to:

{code}

but only {code } File does not exist: /kiran {code} error message should be thrown

{code} } catch (IOException ioe) {
System.err.println("FileSystem is inaccessible due to:\n"
+ StringUtils.stringifyException(ioe));
}{code}

i think it should use ioe.getmessage() method

{code}
} catch (IOException ioe) {
System.err.println("FileSystem is inaccessible due to:\n"
+ StringUtils.stringifyException(ioe.getmessage()));
}
{code}
