HDFS+: Concurrent Writes Improvements for HDFS
2013 13th IEEE/ACM International Symposium on Cluster, Cloud, and Grid Computing, 2013HDFS is a popular distributed file system which provides high scalability and throughput. It lacks built-in support for multi-source data generating, which arise naturally in many applications including log mining, data analysis etc. There needs a data collection step before analysis in basic HDFS environment because of many data are in local disk ...

Commercial dialyzers were investigated both in vivo and in vitro for a better selection of dialyzers for hemodiafiltration (HDF) therapy. In in vivo online HDF, since a reduction rate of α(1)-microglobulin (α(1)-MG) was determined by the amount of albumin loss regardless of blood flow rate (Q(B)), ultrafiltration rate (Q(F)), and the performance of ...

Proceedings of the 23rd international symposium on High-performance parallel and distributed computing, 2014
In this paper, we propose SOR-HDFS, a SEDA (Staged Event-Driven Architecture)-based approach to improve the performance of HDFS Write operation. This design not only incorporates RDMA-based communication over InfiniBand but also maximizes overlapping among different stages of data transfer and I/O.

Effects of Hemodiafiltration versus Conventional Hemodialysis in Children with ESKD: The HDF, Heart and Height Study [PDF]
Journal of the American Society of Nephrology: JASN, 2019 Background Hypertension and cardiovascular disease are common in children undergoing dialysis. Studies suggest that hemodiafiltration (HDF) may reduce cardiovascular mortality in adults, but data for children are scarce.

A Novel Data Encryption in HDFS
2013 IEEE International Conference on Green Computing and Communications and IEEE Internet of Things and IEEE Cyber, Physical and Social Computing, 2013Hadoop distributed file system (HDFS) is an open source software which can be used to build cloud storage system. However, HDFS does not provide any scheme to encrypt user's data. Hence, user needs to encrypt his data locally before transferring to HDFS if he requires high privacy. This paper proposes a novel method to encrypt file while being uploaded.

Secure Hadoop with Encrypted HDFS
2013As Hadoop becomes a popular distributed programming framework for processing large data on its distributed file system (HDFS), demands for secure computing and file storage grow quickly. However, the current Hadoop does not support encryption of storing HDFS blocks, which is a fundamental solution for secure Hadoop.

Research and improvement of HDFS
2014 11th International Computer Conference on Wavelet Actiev Media Technology and Information Processing(ICCWAMTIP), 2014Recently, cloud computing is increasingly becoming the focus of attention at home and abroad. When the big data storage is become the core of cloud computing system, cloud computing system would evolve into a cloud storage system. With rapidly development of cloud computing, cloud storage has become one of most popular research field.
