the real problem is the namenode heap of memory. When History Server try to start, The memory usage of the NameNode climbs quickly to exceed the limit of 1 Gega byte (default configuration) and causes the service to fall. When changing max memory heap to 3 Gb it works fine. I installed previously ambari 2.4.0.1 and i don't seen this behaviour (2.4.2.0 same behaviour as 2.4.1.0). Do you know why?

Hi, in which secction do I increase the memory? HDFS or MapReduce? thanks a lot

Hi Aldo, in HDFS. The parameter is called "NameNode Java heap size".

Hi, thank you for each of you by contributing with insights and experiences.
Just my contribution:
I could install my 1st cluster recently and I have got these behavior from it; a dumb distraction was the cause: I thought /etc/hosts were fine and they were not (missing entries) - fixing them properly and restarting services, they got up promptly - reds became green at end in ambari dashboard.
cheers and good luck
