The contents of the pig script used is as follows:
{code}
define X `./streamingscript/MySimpleStreamApp.pl`
ship('./streamingscript/MySimpleStreamApp.pl');
A = load '/user/pig/tests/data/singlefile/studenttab10k';
B = stream A through X;
store B into 'results_7';
{code}
The streaming script "MySimpleStreamApp.pl" is as follows and it is located
under the streamingscript directory in my home directory. I issued the pig
command from my home directory.
{code}
#!/home/y/bin/perl
while (<>) {
chomp;
print "$_\n";
}
{code}
