Subject [jira] [Commented] (ACCUMULO-2148) Verify upgrade 1.5 to 1.6 works
Date Fri, 04 Apr 2014 23:41:14 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-2148?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13960802#comment-13960802

Sean Busbey commented on ACCUMULO-2148:
---------------------------------------

bq.  Clarify the "if your instance previously upgraded from 1.4 to 1.5" statement to only
apply to recent upgrades (e.g. the 1.4->1.6 path). That may be confusing for people who
have been on 1.5 for some time. Maybe something like "For those attempting to upgrade to 1.6
from 1.4 through 1.5, ..."? That seems a bit wordy too.

If they upgraded from 1.4 to 1.5 with an offline table that has walog entries, that all happened
to be the only things on tablet server that was off (or that ran into problems attempting
to do the copy, it won't matter how long ago it was. Presuming they ever bring the table back
online.

I could maybe explain that the 1.4 to 1.5 upgrade process asynchronously handled migrating
1.4 write ahead logs and that 1.6 can no longer make retries?

bq.  In the last paragraph, quote "metadata" to be clear that we're referring to the table
named "metadata" and not "table metadata".

I did mean "table metadata". We write into multiple tables as a part of the upgrade, not just
into the reserved metadata table. (the new reserved root, for example)
