Bugs with load and store and filenames passed with -param containing periods
----------------------------------------------------------------------------
Key: PIG-754
URL: https://issues.apache.org/jira/browse/PIG-754
Project: Pig
Issue Type: Bug
Reporter: David Ciemiewicz
This one drove me batty.
I have two files file and file.right.
file:
{code}
WRONG!!!!
This is file, not file.right.
{code}
file.right:
{code}
RIGHT!!!!
This is file.right..
{code}
infile.pig:
{code}
A = load '$infile' using PigStorage();
dump A;
{code}
When I pass in file.right as the infile parameter value, the wrong file is read:
{code}
-bash-3.00$ pig -exectype local -param infile=file.right infile.pig
USING: /grid/0/gs/pig/current
2009-04-05 23:18:36,291 [main] INFO
org.apache.pig.backend.local.executionengine.LocalPigLauncher - 100% complete!
2009-04-05 23:18:36,292 [main] INFO
org.apache.pig.backend.local.executionengine.LocalPigLauncher - Success!!
(WRONG!!!! )
(This is file, not file.right.)
{code}
However, if I pass in infile as ./file.right, the script magically works.
{code}
-bash-3.00$ pig -exectype local -param infile=./file.right infile.pig
USING: /grid/0/gs/pig/current
2009-04-05 23:20:46,735 [main] INFO
org.apache.pig.backend.local.executionengine.LocalPigLauncher - 100% complete!
2009-04-05 23:20:46,736 [main] INFO
org.apache.pig.backend.local.executionengine.LocalPigLauncher - Success!!
(RIGHT!!!!)
(This is file.right.)
{code}
I do not have this problem if I use the file name with a period in the script
itself:
infile2.pig
{code}
A = load 'file.right' using PigStorage();
dump A;
{code}
{code}
-bash-3.00$ pig -exectype local infile2.pig
USING: /grid/0/gs/pig/current
2009-04-05 23:22:47,022 [main] INFO
org.apache.pig.backend.local.executionengine.LocalPigLauncher - 100% complete!
2009-04-05 23:22:47,023 [main] INFO
org.apache.pig.backend.local.executionengine.LocalPigLauncher - Success!!
(RIGHT!!!!)
(This is file.right.)
{code}
I also experience similar problems when I try to pass in param outfile in a
store statement.
