I installed HDP 1.3.2 with ambari on VM instance.
I have 2 problems.
1 – Every services are normally operated except for the MapReduce service.
It alerts that “JobTracker CPU utilization – Unable to contact host: ”
2 – CPU % of HDFS master node very high and other nodes are normal. cpu wio hits over 1000 %.
but, In Ganglia monitor, cpu wio is normal under 10%.
Since I had to install HDP on the VM environment, all the ports used in services were opened manually.
I thought that the problem is some ports weren’t opened. so, I tried to open all the ports used in services.
But I didn’t solve the problem.
How can I solve this problem?
Please help me someone who knows.
