Symptoms

On BDA V4.6/CDH 5.8.0 the Navigator Metadata Server unexpectedly exits due to OutOfMemory errors.

The Navigator Server log shows a lot of Errors like:

<TIMESTAMP>,<ID> ERROR com.cloudera.nav.hdfs.client.InotifyClient [CDHExecutor-0-CDHUrlClassLoader@<ID>]:
Error handling event (txid: <TID>): Renamed /hbase/<PATH> to /hbase/<PATH> at time <TIMESTAMP>

 

Additionally the Navigator Server log also shows exceptions like below. These do not appear related to heap exhaustion:
