This is actually a known issue, and there is a Jira for a documentation bug to get this fixed in a later HDP release. Sqoop uses 1.8.0 of avro and there are other Hadoop components using 1.7.5 or 1.7.4 avro.

Please add the following property after 'import': -Dmapreduce.job.user.classpath.first=true

Example:

sqoop import -Dmapreduce.job.user.classpath.first=true -Dhadoop.security.credential.provider.path=jceks://x.jceks --connect jdbc:db2://xxx:60000/x2 --username xx -password-alias xx --as-avrodatafile --target-dir xx/data/test --fields-terminated-by '\001' --table xx -m 1
