Ambari's hive config references hive.metastore.heapsize - is this a real property?

[#1]

Ambari's hive config includes an entry for "Metastore Heap Size" and the context help says this corresponds to hive.metastore.heapsize, but I can't find any other reference to this parameter in Apache or any hadoop vendor's documentation. Is this actually a parameter? Where is it set? The value we are setting in Ambari does not appear to be affecting the actual heap being used on our server.

(Ambari 2.2.2.0)

The hive.metastore.heapsize is not a parameter that is in a file like hive-site.xml. This value is used by Ambari for substitution into the hive-env template file. You can see this section in the text box in Ambari:

if [ "$SERVICE" = "metastore" ]; then
 export HADOOP_HEAPSIZE={{hive_metastore_heapsize}} # Setting for HiveMetastore
else
 export HADOOP_HEAPSIZE={{hive_heapsize}} # Setting for HiveServer2 and Client
fi

The {{hive_metastore_heapsize}} is where the substitution is made.

I think our hive-env template is missing the section related to setting the heapsize.... We're reaching out to support for a fresh copy of that.
