Cloudera Example job Stucking

Hello Guys!

 

I'm having some trouble in running cloudera's example job, as below:

 

hadoop jar /opt/cloudera/parcels/CDH/lib/hadoop-mapreduce/hadoop-mapreduce-examples.jar pi 10 100

 

It's stucking in map, as it's output:

 

[root@cpsmaaeip04 data]# hadoop jar /opt/cloudera/parcels/CDH/lib/hadoop-mapreduce/hadoop-mapreduce-examples.jar pi 10 100
Number of Maps = 10
Samples per Map = 100
Wrote input for Map #0
Wrote input for Map #1
Wrote input for Map #2
Wrote input for Map #3
Wrote input for Map #4
Wrote input for Map #5
Wrote input for Map #6
Wrote input for Map #7
Wrote input for Map #8
Wrote input for Map #9

I have already set for dynamic resource pool 8 VCores and 8GB of memory for the pool root.users. 

 

Do you guys have some clue to solve this issue?
