Subject Upgrade to v3.11.3
Date Wed, 16 Jan 2019 13:44:36 GMT
Hi All,

I'm about to start a rolling upgrade process from version 2.0.14 to version
3.11.3.
I have a few small questions:

   1. The upgrade process that I know of is from 2.0.14 to 2.1.x (higher
   than 2.1.9 I think) and then from 2.1.x to 3.x. Do I need to upgrade first
   to 3.0.x or can I upgraded directly from 2.1.x to 3.11.3?

   2. Can I run upgradesstables on several nodes in parallel? Is it crucial
   to run it one node at a time?

   3. When running upgradesstables on a node, does that node still serves
   writes and reads?

   4. Can I use open JDK 8 (instead of Oracle JDK) with C* 3.11.3?

   5. Is there a way to speed up the upgradesstables process? (besides
   compaction_throughput)


Thanks!
