The various Features of Hadoop are:
Open Source –
Apache Hadoop is an open source software framework. Open source means it is freely available and even we can change its source code as per our requirements.
Distributed processing –
As
HDFS
stores data in a distributed manner across the cluster. MapReduce process the data in parallel on the cluster of nodes.
Fault Tolerance –
Apache Hadoop is highly Fault-Tolerant. By default, each block creates 3 replicas across the cluster and we can change it as per needment. So if any node goes down, we can recover data on that node from the other node. Framework recovers failures of nodes or tasks automatically.
Reliability –
It stores data reliably on the cluster despite machine failure.
High Availability
–
Data is highly available and accessible despite hardware failure. In Hadoop, when a machine or hardware crashes, then we can access data from another path.
Scalability –
Hadoop is highly scalable, as one can add the new hardware to the nodes.
Economic-
Hadoop runs on a cluster of commodity hardware which is not very expensive. We do not need any specialized machine for it.
Easy to use –
No need of client to deal with distributed computing, the framework take care of all the things. So it is easy to use.
