Accumulo upgrade testing in the past has been very minimal and mostly manual. As a result we have run into upgrade bugs in the past. It would be nice to have a framework that makes its easy to run and write upgrade test.
- Can be configured to use existing HDFS and zookeeper instances
- Can be configured with 1.5.x and 1.6.x branches to build
- Supports multiple upgrade scenarios (like clean shutdown, dirty shutdown, etc)
- Runs a set of upgrade test (this would a be a list of test to run thats easy to add to e.g. bulk import upgrade test)
I am thinking the framework could do the following
The framework would configure the Accumulo versions, HDFS, zookeeper, and which test to run.
It would also be use to write the framework in such a way that it could support chaining upgrade test. For example run test that upgrades from 1.4 to 1.5 to 1.6. It possible that a fresh install of 1.5 will upgrade w/o problems, but a 1.5 system was upgraded to 1.4 will not.
