If Hadoop is the CDH
Delete all the export "hadoop_classpath= ..." in the Hplsql file
Add Export "hadoop_classpath=/opt/cloudera/parcels/cdh/jars/*"

If Hadoop is the HDP
Check the/usr/hdp/x.x.x.x-x directory and modify all the export "hadoop_classpath= ..." Paths in the Hplsql file to the/usr/hdp/x.x.x.x-x corresponding path.

For other versions of Hadoop, check the/usr/lib for Hadoop jars and make the corresponding changes in the Phlsql file.

Test whether the installation was successful
/opt/hplsql–version

Cd/opt/hplsql
./hplsql–version

If the above command can return Hplsql version information, the installation is successful.

Add Hplsql to PATH variable
Export path= $PATH:/opt/hplsql

After you set the path, you can call Hpl/sql directly from the Hplsql command.
Hplsql <option>

Use sales_db;
</value>
</property>

Run Hpl/sql
Hplsql-e "Current_date+1"
HPLSQL-E "SELECT * from src LIMIT 1"
Hplsql-f Script.SQL

Using Hpl/sql in shell scripts
Get a value from the Hpl/sql script
mdate=$ (hplsql-e "NVL (min_partition_date (sales,local_dt,code= ' A '), ' 1970-01-01 ')")
