Japan started using Big data analysis

According to Yano research institute LTD, Tokyo Japan, Big data market could reach one trillion yen ($10 billion USD) by 2020 in Japan itself. By utilizing Hadoop on cloud computing, it is possible today to process huge volume of real-time earthquake warning system's data. Seismic data processing is slowly throwing light on accurate earthquake prediction. Besides, in Japan it is helping smart cities to minimize waste and improve efficiency. Oil and Natural gas exploration and production companies now a...

Future of Big Data analysis using Hadoop in Medical Science and Health Care Organizations.

Even though medical sciences are capable of diagnose the diseases like Cancer, Alzheimer’s etc, these diseases remain still incurable. Because to find the root cause of these diseases, the medical researchers need to analyze patient's medical records, various supportive information, climatic conditions in which they lived in, across different geographical locations. And these a need a platform where a huge volume of data can be stored and analyzed. Hadoop is a powerful platform that allows us to store huge...

Opportunities in Big data analysis

Due to invention of Hadoop framework by Apache community, now a days we are capable of processing 100 peta (for example) bytes of data together. And even it could be more. Our present traditional software system are incapable of holding such a huge volume of data which typically we refer as Big Data. By utilizing Hadoop and it's eco system, we can store and process that volume of data in order to find out intricate information. There is a growing...

Performance of Hadoop Map-Reduce

The performance of Hadoop Map-Reduce job can be increased amicably without investing more on the hardware cost. Simply tuning some parameters according to the cluster specifications, input data size and processing complexities. Here are few general tips to improve Map_reduce job performance - Always we should use compression when writing intermediate data (mapper output) to disk before shuffling - Include combiner in the appropriate position. - LongWritable data type is incorrect as output when range of output values are in Integer range. IntWritable...
