Alejandro Fernandez updated AMBARI-17280: ----------------------------------------- Status: Patch Available (was: Open) > RU to write out client configs that are dependencies of Hive, ATS, and Oozie > during upgrades that change configs > ---------------------------------------------------------------------------------------------------------------- > > Key: AMBARI-17280 > URL: https://issues.apache.org/jira/browse/AMBARI-17280 > Project: Ambari > Issue Type: Bug > Components: stacks > Affects Versions: 2.2.0 > Reporter: Ana Gillan > Assignee: Alejandro Fernandez > Priority: Critical > Fix For: 2.4.0 > > Attachments: AMBARI-17280.branch-2.4.patch, AMBARI-17280.trunk.patch > > > During RU, HiveServer2 is restarted but the newer tez configs have not yet > been saved, which is incorrect because Hive has a dependency on Tez. > This is important when configs change during a major stack upgrade, e.g., HDP > 2.4 -> 2.5. 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)
