java - Hadoop job fails when invoked by cron -

-

i have created following shell script invoking hadoop job:

#!/bin/bash /opt/hadoop/bin/hadoop jar /path/to/job.jar com.do.something <param-1> ... <param-n> & wait %1 status=$? if [ $status -eq 0 ]         echo "success" | mailx -s "status: "$status -r "mail@mysite.com" "mail@mysite.com"     exit $status else     echo "failed" | mailx -s "status: "$status -r "mail@mysite.com" "mail@mysite.com"     exit $status fi

when run above script manually this:

$ ./path/to/job.sh

hadoop job executes sucessfully , returns exit status "0".

now, automate job execution everyday, have configured cron job run above script this:

0 22 * * * /path/to/job.sh

but, job not submitted hadoop , exit status "1".

few things note here:

  • the user account under cron job configured usera
  • usera hadoop system user
  • the cluster dedicated running job
  • the script executable

i know why job not running when cron invokes ?

0 22 * * * /path/to/job.sh

i think lost "." in command.

0 22 * * * ./path/to/job.sh

does work?
