Hadoop Cluster Upgrade - July 13 - 18th, 2016

Update: This upgrade is taking substantially longer than expected. Currently we expect the system be available again beginning on August 8, 2016.

The Hadoop cluster (analytics.hpc.uiowa.edu) will be upgraded and will be unavailable from Wednesday July 13th to Monday July 18th.  If you must use the Hadoop cluster in its current configuration and your work will not be finished by July 13th, please let me know as soon as possible and we can consider alternative dates.  This upgrade will focus on Hadoop only.    Here's what will be upgraded:

  • Ambari current version 1.6.1 to version 2.2.2
  • Hadoop current version 2.4.0.2.1 to version 2.7.1
  • Horton Data Platform current version 2.1 to version 2.4
