Migrating to Accumulo 1.10.0
As the Accumulo 1.10 is handled as a different service from Accumulo, in-place upgrade is not supported. However, an in-place data upgrade is supported from any CDH 5, CDH 6, HDP 2, or HDP 3 releases.
Cloudera does not support in-place upgrades because Accumulo is handled as a different service from Accumulo, so the configuration changes would be lost on the upgrade. Please follow the in-place data upgrade process described in the following sections.
