The HDFS High Availability feature addresses the single point of failure issue of a typical Hadoop cluster.
This article describes how to enable your Talend Studio with Big Data to use the HDFS High Availability (HA) feature.
The Studio can be any of the Talend solutions with Big Data.
The Hadoop cluster you are using along with the Studio must support the HDFS HA feature. For further information, see the documentation of that Hadoop distribution you are using.
In the cluster to be used, the properties required by the HDFS High Availability must have been set in the hdfs-site.xml file by the Administrator.
