The HadoopDistributed File System (HDFS) is the underlying filesystem of a Hadoop cluster. The default HDFS dataplacement strategy works well in homogeneouscluster. But it performs poorly in heterogeneousclusters because of the heterogeneity of the nodescapabilities. It may cause overload in somecomputing nodes and reduce Hadoop performance.Therefore, Hadoop Distributed File System (HDFS)has to rely on load balancing utility to balance datadistribution. As a result, data can be placed evenlyacross the Hadoop cluster. But it may cause theoverhead of transferring unprocessed data from slownodes to fast nodes because each node has differentcomputing capacity in heterogeneous Hadoopcluster. In order to solve these problems, adata/replica placement policy based on storageutilization and computing capacity of each data nodein heterogeneous Hadoop Cluster is proposed. Theproposed policy tends to reduce the overload of somecomputing nodes as well as reduce overhead of datatransmission between different computing nodes."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value": []}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2019-07-03"}], "displaytype": "preview", "download_preview_message": "", "file_order": 0, "filename": "28-33.pdf", "filesize": [{"value": "302 Kb"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 302000.0, "url": {"url": "https://meral.edu.mm/record/4343/files/28-33.pdf"}, "version_id": "132f540e-cd6b-421c-a2f5-0e293f335de1"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_issue": "", "subitem_journal_title": "Sixteenth International Conferences on Computer Applications(ICCA 2018)", "subitem_pages": "", "subitem_volume": ""}]}, "item_1583103147082": {"attribute_name": "Conference papers", "attribute_value_mlt": [{"subitem_acronym": "", "subitem_c_date": "", "subitem_conference_title": "", "subitem_part": "", "subitem_place": "", "subitem_session": "", "subitem_website": ""}]}, "item_1583103211336": {"attribute_name": "Books/reports/chapters", "attribute_value_mlt": [{"subitem_book_title": "", "subitem_isbn": "", "subitem_pages": "", "subitem_place": "", "subitem_publisher": ""}]}, "item_1583103233624": {"attribute_name": "Thesis/dissertations", "attribute_value_mlt": [{"subitem_awarding_university": "", "subitem_supervisor(s)": [{"subitem_supervisor": ""}]}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"subitem_authors_fullname": "Soe, Nang Kham"}, {"subitem_authors_fullname": "Yee, Tin Tin"}, {"subitem_authors_fullname": "Htoon, Ei Chaw"}]}]}, "item_1583108359239": {"attribute_name": "Upload type", "attribute_value_mlt": [{"interim": "Publication"}]}, "item_1583108428133": {"attribute_name": "Publication type", "attribute_value_mlt": [{"interim": "Article"}]}, "item_1583159729339": {"attribute_name": "Publication date", "attribute_value": "2018-02-22"}, "item_1583159847033": {"attribute_name": "Identifier", "attribute_value": "http://onlineresource.ucsy.edu.mm/handle/123456789/228"}, "item_title": "Performance-Aware Data Placement Policy for Hadoop Distributed File System", "item_type_id": "21", "owner": "1", "path": ["1597824273898"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000004343", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2019-07-03"}, "publish_date": "2019-07-03", "publish_status": "0", "recid": "4343", "relation": {}, "relation_version_is_last": true, "title": ["Performance-Aware Data Placement Policy for Hadoop Distributed File System"], "weko_shared_id": -1}
