I have a doubt that:
sometime when I run the pig code:
c = stream b through `grep "spider"`;
It will return the error message:
Received Error while processing the map plan: 'grep "spider" ' failed with
exit status: 1
But when I use the pig code:
c = stream b through `awk '{a=index($0,"spider");if(a!=0){print $0};}'`;
It will work normal.
Why?
Thanks very much.
