HDFS

Perform the following pre-transition steps.

Do not change the HA namespace during the upgrade. Changing HA namespace impacts Hive metadata locations and possibly HBase (if the location reference includes the full HDFS location).

  • Preparing HDFS
    Make sure HDFS is healthy.
  • Backup the non-default Rack Awareness Topology script
    Backup any custom configurations of the rack awareness topology script.
