Checking Apache HBase

To upgrade to CDH 6 from CDH 5 and have the HBase service installed, there are several pre-upgrades steps you are required to complete.

When you are attempting to upgrade from a CDH 5 cluster to a CDH 6, checkboxes appear to ensure you have performed all the necessary HBase related pre-upgrade transition step:
  • Remove PREFIX_TREE Data Block Encoding
  • Upgrade co-processor classes
The upgrade continues only if you check both of the following statements:
  • Yes, I have run HBase pre-upgrade checks.
  • Yes, I have manually upgraded the HBase co-processor classes.
