What happens today is, > * Install packages generates /etc/tez/2.5.0.0-1/0 and copies the configs from > /etc/tez/2.4.0.0-1/0/ to the new folder > * If configs change during RU, then Hive is restarted and the classpath means > that it will pick up the older tez configs from the new /etc/tez/2.5.0.0-1/0 > folder > This problem exists for all of these components: > HiveServer: depends on Tez and MapReduce clients > ATS: depends on Tez and Spark clients > Oozie: depends on Tez, Spark, and MapReduce clients > This problem only exists when configs change (so crossing major stack > version) and during RU (because it is allowed to change configs during the > middle of restarting services). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
