Upgrading from Cloudera Manager 5.9 (Navigator 2.8) and earlier can take a significant amount of time, depending on the size of the Navigator Metadata storage directory. When the Cloudera Manager upgrade process completes and Cloudera Navigator services restart, the Solr indexing upgrade automatically begins. No other actions can be performed until Solr indexing completes (a progress message displays during this process). It can take as long as two days to upgrade a storage directory with 60 GB. To help mitigate this extended upgrade step, make sure to clear out all unnecessary metadata using purge, check the size of the storage directory, and consider rerunning purge with tighter conditions to further reduce the size of the storage directory.
Make sure a purge task has run recently to clear stale and deleted entities.
- You can see when the last purge tasks were run in the Cloudera Navigator console (From the Cloudera Manager Admin console, go to Clusters > Cloudera Navigator. Select Administration > Purge Settings.)
- If a purge hasn't run recently, run it by editing the Purge schedule on the same page.
- Set the purge process options to clear out as much of the backlog of data as you can tolerate for your upgraded system. See Managing Metadata Storage with Purge.
Stop the Navigator Metadata Server.
1. Go to Clusters > Cloudera Management Service > Instances.
2. Select Navigator Metadata Server.
3. Click Actions for Selected > Stop.
