h2o starting on YARN not working
You should setup your default queue to have available resources to run 2nodes cluster.
See warnings:
WARNING: Job memory request (2.2 GB) exceeds queue available memory capacity (0.0 GB)- you ask 1GB per node (+overhead) but there is no available resources in the YARN queue
WARNING: Job virtual cores request (2) exceeds queue available virtual cores capacity (0)- you ask for 2 virtual cores but no cores are available in your default queue
Please check YARN documentation - for example setup of capacity scheduler and max available resources:https://hadoop.apache.org/docs/r2.4.1/hadoop-yarn/hadoop-yarn-site/CapacityScheduler.html
I made the following changes in Cloudera Manager yarn configuration
Setting Valueyarn.scheduler.maximum-allocation-vcores 8 yarn.nodemanager.resource.cpu-vcores 4yarn.nodemanager.resource.cpu-vcores 4yarn.scheduler.maximum-allocation-mb 16 GB
