--In this paper, we introduce about the bigdata and big data analytics. A data which is beyond the storage capacity and processing power. We are calling Big Data. Big data analytics is the process of collecting, organizing large data sets containing a variety of data types.

Now a day's online web streaming is one of the most popular activity , websites and applications are the essential part of a life, the need to stream video over networks have increased. Spilling media is sight and sound that is always gotten by and displayed to an end-client while being conveyed by a supplier. The verb "to stream" alludes to the way toward conveying or acquiring media in this way; the term alludes to the conveyance strategy for the medium, instead of the medium itself, and is another option to record downloading, a procedure in which the end-client gets the whole document for the substance before watching or tuning in to it. A customer end-client can utilize their media player to start to play the information record, (for example, an advanced document of a film or tune) before the whole document has been transmitted.
There are various contemplations when transmitting gushing video between the hubs associated through remote systems, for example, throughput, the span of the interactive media document, reaction time, postponement, versatility and loss of information. The adaptability of specially appointed systems should be examined by considering different perspectives, for example, self-association, security, and directing adaptability, accessibility of transfer speed, information circulation, Quality of Service, throughput, reaction time and productivity.
Notwithstanding, endeavours to acknowledge video gushing over wireless ad-hoc networks have addressed numerous difficulties, which are tended to by a few unique strategies. Cases incorporate cross-layer streamlining, reserving and replication, and parcel prioritization. Cross-layer advancement ordinarily uses numerous depiction video coding and multipath steering to give the receiver(s) adequate video quality. Reserving and replication add resilience to interruptions and dividing. . This paper displays an execution assessment of the adaptable video spilling over portable specially appointed systems. We examine the current ways to deal with mixed media directing and transmission over remote specially appointed systems by considering adaptability. The review makes a few determinations and makes suggestions for future headings.

Keywords- Video streaming, Cross-layer design, Mobile ad hoc networks, Multipath routing.

In this paper the authors presented that how to analyse the Customers data when it is huge and various raw format data. So, for this we have used the Hadoop Big Data tools map-reduce Pig and Hive which makes easier to analyse the various raw formats of data.
