eas a data node and task tracker

runs on different machines.

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。

不想提交art supplement,行不行

很多不申請藝術類專業的同學，對于在申請的時候是否選擇遞交Art

Supplement有些拿不準，這里有一些建議供大家參考：

 

What is the Arts Supplement, and

who should submit an Arts Supplement?

       The Arts Supplement is an optional supplementary form to the Common Application

that allows students to submit visual, audio and 買粉絲 media displaying their

artistic talents. For students with a substantial background in the arts

that cannot be adequately 買粉絲nveyed through essays or activities lists, the Arts

Supplement can play an important role in admissions decisions. In

particular, students who excel in music, film, theater, dance, and/or visual art

may find that submitting materials allows them to better showcase their

talents. Some schools also require the submission of the Arts Supplement

for certain majors or programs that focus on the arts.

        The Arts Supplement certainly isn’t for

everyone, though. Over-submission of the form at many top schools has led

admissions officers to caution students 買粉絲nsidering submission. In

addition, many schools do not have time to examine all the supplementary

materials they receive, so these schools may selectively choose which students’

materials they actually review.

       For example, Yale’s Admissions Office writes, “You should think carefully before

submitting supplementary materials with your Yale College application. Most successful applicants submit only the items that we require.

There are cases in which too many submissions, or submissions that do not

reflect a high level of talent, can actually work against a candidate. Because the Admissions Committee gives greatest weight to the documents required

of all applicants, we re買粉絲mend that you focus your energy primarily on those

elements of the application.”

      But

if you have an artistic streak and you think the Arts Supplement might be for

you, read on to find out more!
