Configuring Oozie to use HDFS HA
To 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.
Example:
<action name="mr-node">
<map-reduce>
<job-tracker>${jobTracker}</job-tracker>
<name-node>hdfs://ha-nn</name-node>
where ha-nn is the value of dfs.nameservices
in
hdfs-site.xml
.
