What alternate way does HDFS provides to recover data in case a Namenode..

Answer / Praval Pratap Singh

HDFS provides a mechanism called the Secondary NameNode to periodically backup the NameNode's filesystem image and edit log. In the event of a NameNode failure, a new NameNode can be started with this backup. This backup is not used actively and serves only for recovery purposes.
