Upgrade of HDFS Framework #23

Open elingg opened 9 years ago

elingg commented 9 years ago

Create process for upgrade. Ensure that the framework upgrades successfully without data loss, etc.

Probably just start with an upgrade guide that explains how to upgrade just the scheduler, or the scheduler and executors. Then we can see what the pain points are and figure out how to address them. Do we have a separate issue for upgrading the version of Hadoop/HDFS itself (while leaving hdfs-mesos alone)? I can't find one.

thanks @adam-mesos, I think upgrading the version of Hadoop would be a specific scenario in the upgrade guide. There's upgrading the framework version and then there's upgrading the version of hadoop/hdfs itself. If it makes sense, feel free to create a separate issue for more fine grained tracking.
