Subject [jira] [Commented] (ACCUMULO-4324) Need upgrade testing for 1.8
Date Wed, 22 Jun 2016 16:09:58 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-4324?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15344632#comment-15344632
] 

Michael Wall commented on ACCUMULO-4324:
----------------------------------------

[~kturner] mentioned we needed to add a new DATA_VERSION to prevent things like 1.7 successfully
coming up on a 1.8 instance.  One ticket that I know requires this change is ACCUMULO-1124,
which changed the RFile index.  Anyone know of other tickets that should be listed as part
of this?

I am about to put a PR for this.  Then I want to test an upgrade locally.  Here is my plan.
 
1 - startup 1.7
2 - write some data, scan it
3 - stop Accumulo
4 - startup 1.8 on top of that hdfs/zk
5 - assure can read data, write some more data and scan it
6 - stop Accumulo
7 - try to restart 1.7 and verify it fails

Are there any other things that should be done in testing an upgrade?

> Need to test the upgrade from 1.7 to 1.8.  An rc0 would be helpful for that.
