To add jar files
hive> ADD JAR /.jar;
To add zip files
hive> ADD ARCHIVE /.zip;
To list all files
hive> LIST FILES;
To list all jar files
hive> LIST JARS;
To list all zip files
hive> LIST ARCHIVES;
To delete all zip files
hive> DELETE ARCHIVE /.ZIP;
2) hive-env.sh
hive-env.sh

export HIVE_AUX_JARS_PATH="/home/user/AutoIncrementUDF.jar"
3) hive-site.xml
hive-site.xml

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...

Step 1 - Change the directory to /usr/local/hadoop/sbin. $ cd /usr/local/hadoop/sbin Step 2 - Start all hadoop daemons. $ ./start-all. sh ...
