pig script status running but always remain at zero percent ?

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.

Hello,

I'm facing the same issue but by following the tutorial mentioned in:

https://hortonworks.com/tutorial/hadoop-tutorial-getting-started-with-hdp/section/4/.

Once i execute my pig script, it is stuck in running status as mentioned in status.png.

From RM UI, my application is also stuck in Running status as shown in rm-application.png and i attached the launched job in MapReduce in mr-job.png.

From pig view log, i got hive-log.png.

How can i resolve my issue? I'll be really grateful if you could help me.
