Configuring oozie to use HDFS HA

You can configure an Oozie workflow to use HDFS HA.

Use the HDFS nameservice instead of the NameNode URI in the <name-node> element of the workflow. 
<action name="mr-node">
  <map-reduce>
    <job-tracker>${jobTracker}</job-tracker>
    <name-node>hdfs://ha-nn

where ha-nn is the value of dfs.nameservices in hdfs-site.xml.
