Subject Re: HBASE 2.0 release progress
Date Sat, 12 Nov 2016 02:01:32 GMT
w.r.t. the JIRA filter, I added a clause:

project = HBase AND (fixVersion = 2.0.0 OR affectedVersion = 2.0.0) AND
resolution is EMPTY AND (issuetype != Bug AND issuetype != Test AND
issuetype != Sub-task) and *updatedDate < startOfYear()* ORDER BY issuetype

and got two pages of JIRAs.
These JIRAs haven't been touched for about a year.

Looks like they can be moved to next release if there is no active work
going on.
