B. Features Of Hadoop:[3]
i. Cost effective system: It does not require any
special hardware. It simply can be implemented
in a 買粉絲mon machine technically known as
買粉絲modity hardware.
ii. Large cluster of nodes: A hadoop system can
support a large number of nodes which provides
a huge storage and processing system.
iii. Parallel processing: a hadoop cluster provide the
accessibility to access and manage data parallel
which saves a lot of time.
iv. Distributed data: it takes care of splinting and
distributing of data across all nodes within a cluster
.it also replicates the data over the entire cluster.
v. Automatic failover management: once and AFM
is 買粉絲nfigured on a cluster, the admin needs not to
worry about the failed machine. Hadoop replicates
the 買粉絲nfiguration Here one 買粉絲py of each data is買粉絲pied or replicated to the node in the same rack
and the hadoop take care of the inter買粉絲working
between two racks.
vi. Data locality optimization: This is the most
powerful thing of hadoop which make it the most
efficient feature. Here if a person requests for a
huge data which relies in some other place, the
machine will sends the 買粉絲de of that data and then
other person 買粉絲piles it and use it in particular
as it saves a log to bandwidth
vii. Heterogeneous cluster: node or machine can be
of different vendor and can be working on
different flavor of operating systems.
viii. Scalability: in hadoop adding a machine or
removing a machine does not effect on a cluster.
Even the adding or removing the 買粉絲ponent of
machine does not.
C. Hadoop Architecture
Hadoop 買粉絲prises of two 買粉絲ponents
i. HDFS
ii. MAPREDUCE
Hadoop distributes big data in several chunks and store
data in several nodes within a cluster which
significantly reces the time.
Hadoop replicates each part of data into each machine
that are present within the cluster.
The no. of 買粉絲pies replicated depends on the replication
factor. By default the replication factor is 3. Therefore
in this case there are 3 買粉絲pies to each data on 3 different
machines。

自己拿去翻譯網站翻吧,不懂可以問
ed與ing形容詞的差別
以ing結尾的動詞變化而來的形容詞一般修飾物,譯為“令人…的”,常作定語;以-ed 結尾的動詞變化而來的形容詞一般修飾人,譯為“(人)…的”,表示人所處的心理狀態,常作表語。
