Differentiate HDFS and HBase?

What is the difference between HDFS and HBase?
Comparision between HDFS and HBase?

[DataFlair Team]

HBase is a non-relational database that can run on top of Hadoop and provides you random data access capabilities. HDFS, by itself has no support for reads/writes at random location.

Another primary difference would be the way data is stored in the two. HBase stores data as key/value pairs as in a column database (something similar to Cassandra DB) while in HDFS data stored as flat files.

HBase is an extension for the Hadoop environment that allows you to quickly read/write data.

Let’s compare both on the basis of some features:

HBase vs HDFS

a. Built on

HBase
It is built on top of the HDFS.

HDFS
For storing large files, it is suitable.

b. lookups

HBase
Especially, for larger tables, it offers fast lookups.

HDFS
But it does not offer fast lookups.

C. Latency

HBase
HBase offers low latency access.

HDFS
Whereas, HDFS provides high latency batch processing; yet no support for batch processing.
