    I am using HDP sandbox 2.1. I create a database “hose” in HCatalog, there is a table price_analysis. I create a database hose in mysql and table price_analysis in hose database. I try to execute this below command
    sqoop export –connect jdbc:mysql://localhost:3306/hose –username root –table price_analysis –hcatalog-database ‘hose’ –hcatalog-table ‘price_analysis’

    and it returns me java.lang.NullPointerException
