Hive Web Interface (HWI)

Hive Web Interface (HWI)
The Hive Web Interface is an alternative to using the Hive command line interface. Using the web interface is a great way to get started with Hive. The Hive Web Interface, abbreviated as HWI, is a simple graphical user interface (GUI).
Configuration
Hive Web Interface made its first appearance in the 0.2 branch. If you have Hive release 0.2 or later, or the SVN trunk, then you already have it. You should not need to edit the defaults for the Hive Web Interface. HWI uses:
hive-site.xml
<property>
  <name>hive.hwi.war.file</name>
  <value>lib/hive-hwi-0.12.0.war</value>
  <description>This sets the path to the HWI war file, relative to . </description>
</property>

<property>
  <name>hive.hwi.listen.host</name>
  <value>0.0.0.0</value>
  <description>This is the host address the Hive Web Interface will listen on</description>
</property>

<property>
  <name>hive.hwi.listen.port</name>
  <value>9999</value>
  <description>This is the port the Hive Web Interface will listen on</description>
</property>
To start HWI service
$ HIVE_HOME/bin/hive --service hwi
You can browse to hive web interface at URL
http://localhost:9999/hwi

Apache Spark WordCount scala example

Apache Spark is an open source cluster computing framework. Originally developed at the University of California, Berkeley's AMPLab, the Spark codebase was later donated to the Apache Software Foundation, which has maintained it since. Spark provides an interface for programming entire clusters with implicit data parallelism and fault-tolerance. Pre Requirements 1) A machine with Ubuntu 14.04 LTS operating system 2) Apache Hadoop 2.6.4 pre installed ( How to install Hadoop on Ubuntu 14.04 ) 3) Apache Spark 1.6.1 pre installed ( How to install Spark on Ubuntu 14.04 ) Spark WordCount Scala Example Step 1 - Change the directory to /usr/local/spark/sbin. $ cd /usr/local/spark/sbin Step 2 - Start all spark daemons. $ ./start-all. sh Step 3 - The JPS (Java Virtual Machine Process Status Tool) tool is limited to reporting information on JVMs for which it has the access permissions. $ jp...

Hive hiveserver2 and Web UI usage

Hive hiveserver2 and Web UI usage HiveServer2 (HS2) is a server interface that enables remote clients to execute queries against Hive and retrieve the results (a more detailed intro here). The current implementation, based on Thrift RPC, is an improved version of HiveServer and supports multi-client concurrency and authentication. It is designed to provide better support for open API clients like JDBC and ODBC. Step 1 - Change the directory to /usr/local/hive/bin $ cd $HIVE_HOME/bin Step 2 - Start hiveserver2 daemon $ hiveserver2 OR $ hive --service hiveserver2 & Step 3 - You can browse to hiveserver2 web ui at following url http: //localhost:10002/hiveserver2.jsp Step 4 - You can see the hive logs in /tmp/hduser/hive. log To kill hiveserver2 daemon $ ps -ef | grep -i hiveserver2 $ kill - 9 29707 OR $ rm -rf /var/run/hive/hive...
