Set the Java heap size for the Cloudera Navigator Server to at least 2 GB. If the heap size is not sufficient, the resource load fails with a connection refused error.

Set the maximum heap size for the Metadata Manager Service to at least 4 GB. If you perform simultaneous resource loads, increase the maximum heap size by at least 1 GB for each resource load. For example, to load two Cloudera Navigator resources simultaneously, increase the maximum heap size by 2 GB. Therefore, you would set the

Max Heap Size

property for the Metadata Manager Service to at least 6144 MB (6 GB). If the maximum heap size is not sufficient, the load fails with an out of memory error.
