Dear all,

After installing RDO icehouse successfully, Sahara has been integrated. Unfortunately, I went through many issues and have been resolved using debug mode from the log file. However, was not able to provision a Hadoop Vanilla cluster using Sahara and kept getting the same error message below. The cluster used 1 Master and 3 Slaves. Then tried to use 1 Master and 2 and then 1 Slave. The only combination that brought the cluster to Starting phase in the Dashboard was 1 Master and 1 Slave using 2G RAM and 2 VCP per each instance. The host has 14 GB RAM and 8 CPUs. I ended up by the following debug error trace:

Closing "outdated" since Icehouse is EOL. However, if you're still experiencing this problem with a more recent version, please do reopen.
