There was an email from Infra recently regarding some workspaces which
consume high disk space. Unfortunately the list contains many HBase related
jobs as well.
I went through on all of our jobs and many of these are disabled and
without a single run in the past year. My plan is to delete the jobs below
from builds.apache.org on Friday. Do you think we need any of these jobs so
I should keep them?
HBASE-20112 (still active but change is merged in April 2018)
HBASE-20364 (still active but change is merged in April 2018)
