Hello,    I have a Production cluster and I get out of memory errors for Navigator Metadata Server. This is generating large dump files (33GB last time) in /tmp. Since /tmp has only 50GB it get's full quite fast.  Errors:          The health test result for NAVIGATORMETASERVER_UNEXPECTED_EXITS has become bad: This role encountered 1 unexpected exit(s) in the previous 5 minute(s).This included 1 exit(s) due to OutOfMemory errors. Critical threshold: any. The health test result for NAVIGATORMETASERVER_DATA_DIRECTORY_FREE_SPACE has become unknown: Not enough data to test: Test of whether the Navigator Metadata Server Storage Dir has enough free space.           There is a formula to estimate the optimal Java Heap Size for Navigator Metadata Server but the problem in my case is that in the  cloudera-scm-navigator log file there is no nav_elements nor nav_relations. Is there any way to estimate the optimal java heap size? Current value is set to 24GB. Formula: ((num_nav_elements + num_nav_relations) * 200 bytes) + 2 GB  Link from Cloudera Docs Thank you,   ... View more

Hello,    I'm recently facing an out of memory error for Navigator Metadata Server but I cannot calculate the optimal Java Heap Size for it because in the NAVIGATORMETASERVER log file there are no  nav_elements  neither  nav_relations as explained here: Navigator Metadata Server Tuning. There is no Solr service installed. How can I estimate the optimal java heap size for Navigator Metadata Server in this case?    Thank you, ... View more
