--------------------------------------
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.
