FAQ: How can I tune the node manager configuration in an HortonWorks Hadoop cluster for Enterprise Data Catalog, when the node manager process uses more than two cores and high server CPU utilization is observed?
​In Enterprise Data Catalog (EDC), You can tune the node manager configuration if the node manager Java heap size is lower than 1024 MB.
