s i am installed hadoop using hdp on ec2 amazon cloud. architecture is : 1 node on which ambari server is installed 2 master nodes 3 data nodes So i have total 6 machines in the cluster. Now when i open the pig view in ambari and run my hello world tutorial script a = LOAD 'geolocation' using org.apache.hive.hcatalog.pig.HCatLoader();
b = filter a by event != 'normal';
c = foreach b generate driverid, event, (int) '1' as occurance;
d = group c by driverid;
e = foreach d generate group as driverid, SUM(c.occurance) as t_occ;
g = LOAD 'drivermileage' using org.apache.hive.hcatalog.pig.HCatLoader();
h = join e by driverid, g by driverid; final_data = foreach h generate $0 as driverid, $1 as events, $3 as totmiles, (float) $3/$1 as riskfactor;
store final_data into 'riskfactor' using org.apache.hive.hcatalog.pig.HCatStorer();
Its status changes to accepted and then changes to running but always remain running for hours Then i try to run this script in grunt shell . Here i create new file with the name "vi riskfactor.pig" and run it using the command " pig -useHCatalog -f riskfactor.pig". This job is submitted but never moves from zero percent . Here i attach the screen shots of my console. here i upload the screenshot of installed components in my cluster
