Hi everybody,
today we configured Hadoop Yarn to store its application/jobs data (called
rmstore) from Zookeeper to HDFS. We are going to remove a lot of data from
our Zookeeper cluster in eqiad (several thousands of znodes), hopefully
increasing its reliability (it is shared with all the Kafka clusters at the
moment). This change should be totally transparent for you, but please let
us know in
https://phabricator.wikimedia.org/T216952 if anything looks
weird/different during the next hours/days.
Thanks!
Luca
