             Summary: HPL/SQL COPY FROM FTP Statement: lack of DIR option leads 
to NPE
                 Key: HIVE-13721
                 URL: https://issues.apache.org/jira/browse/HIVE-13721
             Project: Hive
          Issue Type: Bug
          Components: hpl/sql
            Reporter: Carter Shanklin


The docs (http://www.hplsql.org/copy-from-ftp) suggest DIR is optional. When I 
left it out in:

{code}
copy from ftp hdp250.example.com user 'vagrant' pwd 'vagrant'  files 
'sampledata.csv' to /tmp overwrite
{code}

I got:

{code}
Ln:2 Connected to ftp: hdp250.example.com (29 ms)
Ln:2 Retrieving directory listing
  Listing the current working FTP directory
Ln:2 Files to copy: 45 bytes, 1 file, 0 subdirectories scanned (27 ms)
Exception in thread "main" java.lang.NullPointerException

{code}

Traceback leads to:
{code}
  /**
   * Get the target file relative path and name
   */
  String getTargetFileName(String file) {
    int len = dir.length();
    return targetDir + file.substring(len);
  }
{code}
in Ftp.java

When I added DIR '/' this worked.
