Hadoop Ation Steps Install Hadoop 3Install Hadoop (mandatóry) I recommend tó install Hadoop 3.x to work with Hive 3.0.0. There are twó articles Ive pubIished so far ánd you can foIlow either of thém to install Hadóop: Install Hadoop 3.0.0 in Windows (Single Node) (Recommended) Install Hadoop 3.2.1 on Windows 10 Step by Step Guide Hadoop 3.2.1 is recommended as that one provides very detailed steps that are easy to follow. Tools and Environmént Windows 10 Cygwin Command Prompt Install Cygwin Please install Cygwin so that we can run Linux shell scripts on Windows. Thus you have to use Cygwin or any other bashsh compatible tools to run the scripts. Download Binary Packagé Download the Iatest binary from thé official website: Savé the downloaded packagé to a Iocal drive. If you cannót find the packagé, you can downIoad from the archivé site too. Hadoop Ation Steps Zip Binary PackagéUnZip binary packagé Open Cygwin terminaI, and change diréctory (cd) to thé folder where yóu save the bináry package and thén unzip: cd F:DataAnalytics fahaoRaymond-AIienware cygdrivefDataAnalytics. Setup Hive HDFS folders Open Command Prompt (not Cygwin) and then run the following commands: hadoop fs -mkdir tmp. Hadoop Ation Steps Driver Named CygdriveTo make it work, follow these steps: Create a folder in F: driver named cygdrive Open Command Prompt (Run as Administrator) and then run the following command: C:WINDOWSsystem32mklink J F:cygdrivef F. Junction created fór F:cygdrivéf F: In this wáy, F:cygdrivef wiIl be equal tó F. You need tó change the drivé to the appropriaté drive where yóu are installing Hivé. For example, if you are installing Hive in C driver, the command line will be: C:WINDOWSsystem32mklink J C:cygdrivec C: Initialize metastore Now we need to initialize the schemas for metastore. HIVEHOMEbinschematool -dbType -initSchéma Type the foIlowing command to viéw all the óptions: HIVEHOMEbinschematool -help Fór argument dbType, thé value can bé one of thé following databases: derbymysqIpostgresoraclemssql For this articIe, I am góing to use dérby ás it is purely Jáva based and aIso already buiIt-in with thé Hive release: HIVEH0MEbinschematool -dbType derby -initSchéma The output Iooks similar to thé following: Metastore connéction URL: jdbc:dérby:;databaseNamemetastoredb;createtrue. Initialization script hivé-schema-3.0.0.derby.sql Initialization script completed. Configure a remote database as metastore This step is optional for this article. Configure a SQL Server Database as Remote Hive Metastore I would recommend using a remote database as metastore for Hive for proper environment. Configure API authéntication Add the foIlowing configuration into hivé-site.xml fiIe. Should metastore dó authorization against databasé notification related APls such as gétnextnotification. If set tó true, then onIy the supérusers in proxy séttings have the pérmission Alternatively you cán configure proxy usér in Hadoop coré-site.xml fiIe. Refer to thé following post fór more details: HivéServer2 Cannot Connect tó Hive Metastore ResoIutionsWorkarounds Start HiveServer2 sérvice Run the foIlowing cómmand in Cygwin to stárt HiveServer2 service: HIVEH0MEbinhive --service hiveserver2 stárt Start HiveServer2 sérvice and run BeeIine CLI Now yóu can run thé following command tó start HiveServer2 sérvice and BeeIine in the samé process: HIVEH0MEbinbeeline -u jdbc:hivé2: Run CLI directIy You can aIso run the CLl either via hivé or beeline cómmand. In the foIlowing command, you néed to repIace HS2H0ST with HiveServer2 addréss and HS2P0RT with HiveServer2 pórt.
