Mysql version: 5.7.19-0ubuntu0.17.04.1 Hive version: version 2 Hadoop version: 2.7.1

Answer 1

Your data seems to have been imported to hadoop system from mysql successfully. So incompatibility is between hadoop and hive jar's. Log says, its a connectivity issue with hive metasotre. So, could you please validate the hive-common jar version in hive-site.xml and in hive lib?

Answer 2

What I did is I made sure I copied hive-site.xml to sqoop conf folder mine looks like this /opt/sqoop/conf/ . Once I did that it worked.!!.
