I have a table in Hive, named table_hive and I want it export to mysql database(mydatabase), table_mysql on server2. I submit sqoop export job from server1 on which sqoop client is installed. After submit, it tries to connect server1's mysql database as if it were, which is not. I don't understand why it tries to connect server1 although command --connect parameter indicates server2. sqoop export --connect jdbc:mysql://server2:3306/mydatabase --username user --password password --table table_mysql --export-dir /apps/hive/warehouse/staging.db/table_hive Error codes: /usr/hdp/2.6.3.0-235//sqoop/conf/sqoop-env.sh: line 21: HADOOP_CLASSPATH=${hcat -classpath}: bad substitution
Warning: /usr/hdp/2.6.3.0-235/accumulo does not exist! Accumulo imports will fail.
Please set $ACCUMULO_HOME to the root of your Accumulo installation.
