Exception when hive submits M/R jobs

I have a new Hive installation . Im able to create  tables and do select * queries from them.  But as soon as I try to execute a query that would involve a Hadoop M/R job,  I get this exception .

java.lang.IllegalArgumentException: Can not create a Path from an empty string
        at org.apache.hadoop.fs.Path.checkPathArg(Path.java:82)
        at org.apache.hadoop.fs.Path.<init>(Path.java:90)

        at org.apache.hadoop.mapred.JobClient.submitJob(JobClient.java:807)

The table is pretty simple .  It is an external table on the  HDFS  and does not have  any partitions.       Any idea why this could be happening ?

Thanks,
Sam William
