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.
