Does any big data technology belong to hadoop ecosystem if it uses hdfs?

[Monica Shiralkar]

Hadoop ecosystem comprises of technologies like hdfs, map reduce , hbase ,hive etc . It also has technologies such as mahoot ,oozie ,impala,zookeeper.

How are big data technologies classified into belonging to hadoop ecosystem or not ? I can see one common factor that map reduce ,hive and hbase all use hdfs .Does that mean whichever big data technology uses hdfs comes under hadoop ecosystem ?

Both the words Hadoop ecosystem and Big data Technologies are quite interlinked and depend on each other for existence !

Theoretically, as you mentioned Hadoop ecosystem is an environment comprising of all technologies used in it, its a package all together like HDFS is way of how file can be stored, different than map-reduce which is how the processing can be done, and hive for query to HDFS and so on......

Big Data technology is anything that can store, retrieve and process volumetric data in speed, so at the moment Hadoop ecosystem is what can do it and thereby two are used interchangeably !  In future you may have some technology not Hadoop ecosystem which can deal with volumes of data then that would come under Big data although not Hadoop !!

Thanks.
And What is the criteria for classifying whether any technology is under hadoop ecosystem.?

E.g Spark does not come under Hadoop.
Hbase comes under hadoop, so does  mahoot,kafka etc.

Is the criteria that if a technology uses HDFS then it comes under hadoop ?
