HDFS is a Hadoop distributed file system, it was developed to support distributed designs of file system. It is based on java and is scalable and reliable for data storage. Low cost hardware's are required to design HDFSwith high fault tolerant.Data is replicated in HDFS across clusters.In case of failure of single process, then also computation is continued without stopping process.No restrictions are there on storage of datasets in HDFS.Both structured and schema less data is supported by it.
