---------------------------------------

             Summary: Hive HCat does not create a proper "client" on kerberos cluster without hive metastore
                 Key: HIVE-20348
                 URL: https://issues.apache.org/jira/browse/HIVE-20348
             Project: Hive
          Issue Type: Bug
            Reporter: Oleksiy Sayankin
            Assignee: Oleksiy Sayankin


*STEPS TO REPRODUCE:*

1. Configure Hive to use embedded Metastore (do not specify {{hive.metastore.uris}} in {{hive-site.xml}});

2. Create a database and a table in MySQL:
{code:java}
mysql -uroot -p123456 -e "CREATE DATABASE test;CREATE TABLE test.test (id INT);INSERT INTO test.test VALUES (1),(2),(3)"
{code}

3. Create a table in Hive:

{code:java}
hive -e "CREATE TABLE default.test (id INT)"
{code}

4. Run Sqoop import command:

{code:java}
sqoop import --connect 'jdbc:mysql://localhost:3306/test' --username root --password 123456 --table test  --hcatalog-database "default" --hcatalog-table "test" --verbose -m 1
{code}


*ACTUAL RESULT:*

Sqoop import command fails with an exception:
