| Step1: Make sure OpenJDK8 is installed by typing: $ java -version NOTE: If this step fails, then fail the test |
| Step2: Follow the steps of Installation from wiki 'https://wiki.linaro.org/LEG/Engineering/BigData/Installing_Hadoop_2_7_2_Spark_2_0_Hive_2_1_0' |
| Step3: To configure Hive with Hadoop, you need to edit the hive-env.sh file, which is placed in the $HIVE_HOME/conf directory. The following commands redirect to Hive config folder and copy the template file: $ cd $HIVE_HOME/conf $ cp hive-env.sh.template hive-env.sh |
| Step4: Edit the hive-env.sh file by appending the following line: $ export HADOOP_HOME=/usr/local/hadoop |
| Step5: Derby is required to test Hive. Follow the steps to download and install apache derby. For Ref - wiki https://wiki.linaro.org/LEG/Engineering/BigData/Hive#Downloading_Apache_Derby $ cd ~ $ wget http://archive.apache.org/dist/db/derby/db-derby-10.4.2.0/db-derby-10.4.2.0-bin.tar.gz $ tar zxvf db-derby-10.4.2.0-bin.tar.gz $ su - passwd: # cd /home/user # mv db-derby-10.4.2.0-bin /usr/local/derby # exit |
| Step6: Configure Environment for Derby, by following the steps: $ export DERBY_HOME=/usr/local/derby $ export PATH=$PATH:$DERBY_HOME/bin $ export CLASSPATH=$CLASSPATH:$DERBY_HOME/lib/derby.jar:$DERBY_HOME/lib/derbytools.jar |
| Step7: Create a directory to store Hive MetaStore $ mkdir $DERBY_HOME/data |
| Step8: Configure Metastore for Hive. $ cd $HIVE_HOME/conf $ cp hive-default.xml.template hive-site.xml |
| Step9: Edit hive-site.xml and append the following lines between the and tags: javax.jdo.option.ConnectionURL jdbc:derby://localhost:1527/metastore_db;create=true JDBC connect string for a JDBC metastore |
| Step10: Create a file named jpox.properties and add the following lines into it: javax.jdo.PersistenceManagerFactoryClass = org.jpox.PersistenceManagerFactoryImpl org.jpox.autoCreateSchema = false org.jpox.validateTables = false org.jpox.validateColumns = false org.jpox.validateConstraints = false org.jpox.storeManagerType = rdbms org.jpox.autoCreateSchema = true org.jpox.autoStartMechanismMode = checked org.jpox.transactionIsolation = read_committed javax.jdo.option.DetachAllOnCommit = true javax.jdo.option.NontransactionalRead = true javax.jdo.option.ConnectionDriverName = org.apache.derby.jdbc.ClientDriver javax.jdo.option.ConnectionURL = jdbc:derby://hadoop1:1527/metastore_db;create = true javax.jdo.option.ConnectionUserName = APP javax.jdo.option.ConnectionPassword = mine |
| Step11: Create a tmp directory before running hive and give write permissions $ mkdir tmp $ chmod g+w |
| Step12: Set up HDFS before verifying Hive $ $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 |
| Step13: Verify Hive Installation, by typing the following command to create Hive shell $HIVE_HOME/bin/hive |
| Step14: Run show tables command hive> show tables; |
| Step15: Type the following command to exit Hive shell hive> quit |
