extends Object

Test migration that changes HRI serialization into PB. Tests by bringing up a cluster from actual data from a 0.92 cluster, as well as manually downgrading and then upgrading the hbase:meta info.

Deprecated.

This test assumes a master crash/failure during the meta migration process and attempts to continue the meta migration process when a new master takes over. When a master dies during the meta migration we will have some rows of META.CatalogFamily updated with PB serialization and some still hanging with writable serialization. When the backup master/ or fresh start of master attempts the migration it will encounter some rows of META already updated with new HRI and some still legacy. This test will simulate this scenario and validates that the migration process can safely skip the updated rows and migrate any pending rows at startup.

Throws:

Exception
