Heap Size Configuration

Before you create a Cloudera Navigator resource, you must configure the Java heap size for the Cloudera Navigator server and the maximum heap size for the Metadata Manager Service. If you do not correctly configure the heap sizes, the metadata load can fail.

Configure the following heap sizes:

Java heap size for the Navigator server: Before you create a Cloudera Navigator resource, 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.
Maximum heap size for the Metadata Manager Service: Before you create a Cloudera Navigator resource, open the Administrator tool and check the value of the
Max Heap Size
property for the Metadata Manager Service. Set the maximum heap size to at least 4096 MB (4 GB).

If you perform simultaneous resource loads, increase the maximum heap size by at least 1024 MB (1 GB) for each resource load. For example, to load two Cloudera Navigator resources simultaneously, increase the maximum heap size by 2048 MB (2 GB). Therefore, you would set Max Heap Size to at least 6144 MB.

Some Cloudera distributions might require a maximum heap size larger than 4 GB. If the metadata load fails with an out of memory error, increase the maximum heap size.
