Orchestrating Big Data Analysis Workflows in the Cloud: Research Challenges, Survey, and Future Directions
00 Orchestrating Big Data Analysis Workflows in the Cloud: Research Challenges, Survey, and Future Directions MUTAZ BARIKA, University of Tasmania SAURABH GARG, University of Tasmania ALBERT Y. ZOMAYA, University of Sydney LIZHE WANG, China University of Geoscience (Wuhan) AAD VAN MOORSEL, Newcastle University RAJIV RANJAN, Chinese University of Geoscienes and Newcastle University Interest in processing big data has increased rapidly to gain insights that can transform businesses, government policies and research outcomes. This has led to advancement in communication, programming and processing technologies, including Cloud computing services and technologies such as Hadoop, Spark and Storm. This trend also affects the needs of analytical applications, which are no longer monolithic but composed of several individual analytical steps running in the form of a workflow. These Big Data Workflows are vastly different in nature from traditional workflows. Researchers arecurrently facing the challenge of how to orchestrate and manage the execution of such workflows. In this paper, we discuss in detail orchestration requirements of these workflows as well as the challenges in achieving these requirements. We alsosurvey current trends and research that supports orchestration of big data workflows and identify open research challenges to guide future developments in this area.

Several approaches have been developed in this context proposing the storage and querying of RDF data in a distributed fashion, mainly using the MapReduce Programming Model and Hadoop-based ecosystems. New trends in Big Data technologies have also emerged (e.g., Apache Spark, Apache Flink); they use distributed in-memory processing and promise to deliver higher data processing performance. In this paper, we present a formal interpretation of some PACT transformations implemented in the Apache Flink DataSet API. We use this formalization to provide a mapping to translate a SPARQL query to a Flink program. The mapping was implemented in a prototype used to determine the correctness and performance of the solution.

Large Scale Querying and Processing for Property Graphs Phd Symposium∗
Large Scale Querying and Processing for Property Graphs PhD Symposium∗ Mohamed Ragab Data Systems Group, University of Tartu Tartu, Estonia [email protected] ABSTRACT Recently, large scale graph data management, querying and pro- cessing have experienced a renaissance in several timely applica- tion domains (e.g., social networks, bibliographical networks and knowledge graphs). However, these applications still introduce new challenges with large-scale graph processing. Therefore, recently, we have witnessed a remarkable growth in the preva- lence of work on graph processing in both academia and industry. Querying and processing large graphs is an interesting and chal- lenging task. Recently, several centralized/distributed large-scale graph processing frameworks have been developed. However, they mainly focus on batch graph analytics. On the other hand, the state-of-the-art graph databases can’t sustain for distributed Figure 1: A simple example of a Property Graph efficient querying for large graphs with complex queries.

Debugging Spark Applications a Study on Debugging Techniques of Spark Developers
Debugging Spark Applications A Study on Debugging Techniques of Spark Developers Master Thesis Melike Gecer from Bern, Switzerland Philosophisch-naturwissenschaftlichen Fakultat¨ der Universitat¨ Bern May 2020 Prof. Dr. Oscar Nierstrasz Dr. Haidar Osman Software Composition Group Institut fur¨ Informatik und angewandte Mathematik University of Bern, Switzerland Abstract Debugging is the main activity to investigate software failures, identify their root causes, and eventually fix them. Debugging distributed systems in particular is burdensome, due to the challenges of managing numerous devices and concurrent operations, detecting the problematic node, lengthy log files, and real-world data being inconsistent. Apache Spark is a distributed framework which is used to run analyses on large-scale data. Debugging Apache Spark applications is difficult as no tool, apart from log files, is available on the market. However, an application may produce a lengthy log file, which is challenging to examine. In this thesis, we aim to investigate various techniques used by developers on a distributed system. In order to achieve that, we interviewed Spark application developers, presented them with buggy applications, and observed their debugging behaviors. We found that most of the time, they formulate hypotheses to allay their suspicions and check the log files as the first thing to do after obtaining an exception message. Afterwards, we use these findings to compose a debugging flow that can help us to understand the way developers debug a project. i Contents -
