MapR is a San Jose, California-based enterprise software company that develops and sells Apache Hadoop-derived software. The company contributes to Apache Hadoop projects like HBase, Pig (programming language), Apache Hive, and Apache ZooKeeper.〔(【引用サイトリンク】title=Why MapR is Right to Give Back to Apache Hadoop )〕 MapR's Apache Hadoop distribution claims to provide full data protection, no single points of failure, improved performance, and dramatic ease of use advantages. MapR entered a technology licensing agreement with EMC Corporation on 25 May 2011, supporting an EMC-specific distribution of Apache Hadoop.〔(【引用サイトリンク】title=Startup MapR Underpins EMC’s Hadoop Effort )〕 MapR was selected by Amazon to provide an upgraded version of Amazon's Elastic Map Reduce (EMR) service.〔(【引用サイトリンク】title=Amazon EMR with the MapR Distribution for Hadoop )〕〔(【引用サイトリンク】title=Amazon Taps MapR for High Powered Elastic Map Reduce )〕 MapR has also been selected by Google as a technology partner.〔(【引用サイトリンク】url=http://www.reuters.com/article/2012/07/24/idUS189111+24-Jul-2012+BW20120724 )〕 MapR was able to break the minute sort speed record on Google's compute platform. MapR provides three versions of their product known as M3, M5 and M7. M3 is a free version of the M5 product with degraded availability features. M7 is like M5, but adds a purpose built rewrite of HBase that implements the HBase API directly in the file-system layer. MapR is privately held with original funding of $9 million from Lightspeed Venture Partners and New Enterprise Associates since 2009. Key MapR executives come from Google, Lightspeed Venture Partners, Informatica, EMC Corporation and Veoh. MapR had an additional round of funding led by Redpoint in August, 2011.〔(【引用サイトリンク】title=MapR Technologies Secures 20 million in Funding )〕〔(【引用サイトリンク】title=MapR Makes Friends of Hadoop )〕 A C round was led by Mayfield Fund that also included Greenspring Associates as an investor. In June 2014, MapR closed a $110 million financing round that was led by Google Capital. Qualcomm Ventures also participated, along with existing investors Lightspeed Venture Partners, Mayfield Fund, New Enterprise Associates and Redpoint Ventures. ==Partners== * Amazon offers MapR's M3 and M5 editions as premium options on the Elastic MapReduce service next to a set of Apache Hadoop versions.〔 * Big Data Partnership partners with MapR as first Certified Training & SI partner in EMEA * Google partnered with MapR in the launch of the Google Compute Engine. * Cisco Systems announced support of MapR software on the Cisco Unified Computing System platform.〔(【引用サイトリンク】url=http://www.cisco.com/en/US/solutions/collateral/ns340/ns517/ns224/ns944/le_38203_sb_mapr_130208.pdf )〕 * Informatica Corporation * Impetus Technologies * Talend * Teradata Corporation * Tata Consultancy Services〔http://www.business-standard.com/article/companies/tcs-partners-with-mapr-technologies-to-make-new-big-data-offerings-114072201086_1.html〕 * Databricks 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「MapR」の詳細全文を読む スポンサード リンク
