The following page has been changed by RaghuAngadi: http://wiki.apache.org/lucene-hadoop/Hadoop_0%2e14_Upgrade New page: = Upgrade Guide for Hadoop-0.14 = This page describes upgrade information that is specific to Hadoop-0.14. The usual upgrade described in [:Hadoop_Upgrade: Hadoop Upgrade page] still applies for Hadoop-0.14. == Brief Upgrade Procedure == In most cases, upgrade to Hadoop-0.14 completes without any problems. In these case, administrators do not need to rest of the sections in this document. The simple upgrade steps are same as listed in [:Hadoop_Upgrade:Hadoop Upgrade]: 1. If you are running Hadoop-0.13.x, make sure the cluster is finalized. 1. Stop map-reduce cluster(s) and all client applications running on the DFS cluster. 1. Stop DFS using the shutdown command. 1. Install new version of Hadoop software. 1. Start DFS cluster with –upgrade option. 1. Wait for for cluster upgrade to complete. 6. Start map-reduce cluster. 7. Verify the components run properly and finalize the upgrade when convinced. The rest of the document describes what happens once the cluster is started with {{{-upgrade}}} option.
