Preparing Spark for upgrade
You must migrate catalog data from dual catalog mode to single catalog mode before you upgrade HDP 3.1.5.x to HDP intermediate bits.
- Cloudera supports only a single catalog HDP 3.1.5 upgrade to CDP Private Cloud Base 7.1.6.
- If your cluster version is HDP 3.1.4 or less, then you must upgrade to HDP 3.1.5 and then migrate to the single catalog.
- You must validate that all the tables are present in the single shared catalog.
