    [ https://issues.apache.org/jira/browse/HDFS-14762?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16920303#comment-16920303 ] 

hemanthboyina commented on HDFS-14762:
--------------------------------------

{code:java}
    // add "./" in front of Linux relative paths so that a path containing
    // a colon e.q. "a:b" will not be interpreted as scheme "a".
    if (!WINDOWS && path.charAt(0) != '/') {
      path = "./" + path;
    } {code}
for linux , if the path given was a:b , it should be as ./a:b
adding a patch shortly
