I was doing some experiments in pig(hadoop mode). I loaded the sample data into HDFS ,
a A 1 b B 2 c C 3 a AA 11 a AAA 111 b BB 22
hdfs://#######/data/one
Then I logged into grunt shell, I fired the ls. I can able to see the file in the hdfs.
I loaded the data like this: data = load 'data/one' using PigStorage();
Then I fired the dump data but I'm getting the error like this
Failed Jobs:
JobId Alias Feature Message Outputs
job_201111102206_22874 data MAP_ONLY Message: Job failed! Error - Job initialization failed:

2011-12-17 23:48:32,689 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 1066: Unable to open iterator for alias <b>data</b>
This same process I had executed many times, it worked for me but not now and this is also working well in local mode.
And last thing , I had the checked the data, there is no unnecessary space.
Any suggestion?
