Running Hive

Hive uses hadoop that means; as prerequisites:

• you must have hadoop in your path OR
• export HADOOP_HOME=<hadoop-install-dir>

In addition, you must create /tmp and /user/hive/warehouse
(aka hive.metastore.warehouse.dir) and set them chmod g+w in
HDFS before you can create a table can be created in Hive.

Commands to perform this setup

  $ $HADOOP_HOME/bin/hadoop fs -mkdir       /tmp
  $ $HADOOP_HOME/bin/hadoop fs -mkdir       /user/hive/warehouse
  $ $HADOOP_HOME/bin/hadoop fs -chmod g+w   /tmp
  $ $HADOOP_HOME/bin/hadoop fs -chmod g+w   /user/hive/warehouse

I also You may find it useful but , though it's not necessary, to set HIVE_HOME

  $ export HIVE_HOME=<hive-install-dir>

Configuration management overview

• Hive by default gets its configuration is stored in from <install-dir>/conf/hive-default.xml
• The location of the Hive configuration directory can be changed by setting the HIVE_CONF_DIR environment variable.
• Configuration variables can be changed by (re-)defining them in <install-dir>/conf/hive-site.xmlThe location of the Hive configuration directory can be changed by setting the HIVE_CONF_DIR environment variable.
• Log4j configuration is stored in <install-dir>/conf/hive-log4j.properties

• Hive configuration is an overlay on top of hadoop - meaning it inherits the hadoop configuration variables are inherited by default.

• Hive configuration can be manipulated by:
