In 2.0, Kylin has full HA !!
In 1.X has close to HA
- it has HA to run your queries
- it doesn't have HA to calculate cubes
Check this <http://kylin.apache.org/docs15/install/kylin_cluster.html>: you
can have 'n' queries nodes (to solve node) and use a Load Balancer to
distribute the load (MailList
<http://mail-archives.apache.org/mod_mbox/kylin-user/201701.mbox/%3CF67A65A186263E4F9EF49BEAEEB50CFE2EAD5D9B03%40ME-MEL-EX1.migrationexpert.com%3E>
)
About the job node, You need it to create new cubes and job scheduler, in
KYLIN-2006 <https://issues.apache.org/jira/browse/KYLIN-2006> v2.0.0 has HA
Either way, with 1.6 if job node fail they auto-resume pending task at
failure point (without data lost) (MailList
