Subject Re: Ambari Server going Out Of Memory?
Date Tue, 01 Dec 2015 15:27:11 GMT
Hello. This is JVM error, and not Ambari one.
It basically says that theres not enough memory at host to handle heap of allowed size (2GB
by default).
In your case it tries to allocate ~400MB and is unable to do so.
May be some other application consumed all available memory.

While checking the logs and trying to restart the Ambari Server I see following error.
