Hudson commented on AMBARI-13723: --------------------------------- ABORTED: Integrated in Ambari-trunk-Commit #3774 (See [https://builds.apache.org/job/Ambari-trunk-Commit/3774/]) AMBARI-13723. Express Upgrade: HDP 2.1->2.3 must uninstall 2.1 bits (afernandez: [http://git-wip-us.apache.org/repos/asf?p=ambari.git&a=commit&h=67e069ef37400221ced55356f215ab591f8798ea]) * ambari-server/src/main/resources/custom_actions/scripts/remove_bits.py * ambari-server/src/main/resources/stacks/HDP/2.1/upgrades/nonrolling-upgrade-2.3.xml > Express Upgrade: HDP 2.1->2.3 must uninstall 2.1 bits before starting on 2.3 > ---------------------------------------------------------------------------- > > Key: AMBARI-13723 > URL: https://issues.apache.org/jira/browse/AMBARI-13723 > Project: Ambari > Issue Type: Story > Components: ambari-server > Affects Versions: 2.2.0, 2.1.3 > Reporter: Alejandro Fernandez > Assignee: Alejandro Fernandez > Fix For: 2.2.0, 2.1.3 > > Attachments: AMBARI-13723.trunk.patch > > > We found a major flaw in the Express Upgrade from 2.1->2.3. Basically, > "hadoop" bin still points to the old binary because we had to install HDP 2.3 > while 2.1 bits still existed. > *Manual Upgrade Instructions:* > * Stop all services using 2.1 > * yum erase hadoop hdfs hive … (this will remove scripts /usr/bin/hadoop, > /usr/bin/hdfs, /usr/bin/hive, etc/) > * yum install hadoop_2_3_* hdfs_2_3_* hive_2_3_* (rpm should point > /usr/bin/hadoop -> /usr/hdp/current/hadoop-client/bin/hadoop) > * Change the version to 2.3 (hdp-select, conf-select, etc.) > * Start all services, and hence MR Service Check passes with "hadoop" command > *Express Upgrade:* > * Install HDP 2.3 bits. We reused the RU framework that relies on a 2 step > process: install bits, perform upgrade. Hence, /usr/bin/hadoop is still using > 2.1 bits > * Stop all services using 2.1 > * Change the version to 2.3 (hdp-select, conf-select, etc.) > * Start all services, will fail on MR Service Check because ExecuteHadoop() > resource calls "hadoop" command, which is still pointing to 2.1 bits! > One solution is for the orchestration to remove the 2.1 bits before starting > using 2.3. > Uninstalling the 2.1 bits will remove /usr/bin/hadoop, but when we call > "hdp-select set hadoop-client <new_version>" it will create the symlink > /usr/bin/hadoop -> /usr/hdp/current/hadoop-client/bin/hadoop -- This message was sent by Atlassian JIRA (v6.3.4#6332)
