To start Beeline in embedded mode and connect to Hive using a connection string !connect jdbc:hive2://, By running this command it prompts for user name and password. The name of the log entry is "HiveMetaStore.audit". HiveServer2 by default provides user scott and password tiger, so let's use these default credentials. To run HiveServer2 and Beeline from shell: Beeline is started with the JDBC URL of the HiveServer2, which depends on the address and port where HiveServer2 was started. Creating a new key in the offline registry editor 7. at com.mysql.jdbc.ConnectionImpl.connectOneTryOnly(ConnectionImpl.java:2370) at com.mysql.jdbc.MysqlIO.doHandshake(MysqlIO.java:1300) By default HiveServer2 runs on port 10000, If you wanted to change the port, you can do it by changing the value for hive.server2.thrift.port property on $HIVE_HOME/conf/hive-site.xml file. In order to obtain the performance metrics via the PerfLogger, you need to set DEBUG level logging for the PerfLogger class (HIVE-12675). $ $HIVE_HOME/bin/schematool -dbType <db type> -initSchema HiveServer2 (introduced in Hive 0.11) has its own CLI called Beeline. at com.mysql.jdbc.ConnectionImpl.coreConnect(ConnectionImpl.java:2337) From here, you can try a few simple commands to get a feel for this simple command line interface. Starting with release 0.7, Hive also supports a mode to run map-reduce jobs in local-mode automatically.

By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. I have no database named metastore. These jobs are then submitted to the Map-Reduce cluster indicated by the variable: While this usually points to a map-reduce cluster with multiple nodes, Hadoop also offers a nifty option to run map-reduce jobs locally on the user's workstation. About an argument in Famine, Affluence and Morality, Styling contours by colour and by line thickness in QGIS, Topological invariance of rational Pontrjagin classes for non-compact spaces. The logs are stored in the directory /tmp/: To configure a different log location, sethive.log.dir in$HIVE_HOME/conf/hive-log4j.properties. Right now, in the default configuration, this metadata can only be seen by one user at a time. What Is the Difference Between 'Man' And 'Son of Man' in Num 23:19? at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:935) at com.mysql.jdbc.ConnectionImpl. Linux is supported by a number of Hadoop projects, including Hive, Pig, and HBase. Starting with release 0.6 Hive uses the hive-exec-log4j.properties (falling back to hive-log4j.properties only if it's missing) to determine where these logs are delivered by default.
