Migrating Accumulo to Cloudera

As Operational Database powered by Apache Accumulo is handled as a different service from Accumulo, in-place upgrade is not supported. However, an in-place data upgrade is supported from CDH 6 to Cloudera, or you can migrate your data and configuration to Operational Database.

Cloudera does not support in-place upgrade because Operational Database is handled as a different service from Accumulo, so the configuration changes would be lost on upgrade. You can use the migration steps to migrate from Accumulo 1.x to Operational Database, or if you are migrating from CDH 6 to Cloudera, you can follow the in-place data upgrade process.
