import - Getting error while trying to connect to mysql server from sqoop -

-

i using cloudera cdh practising sqoop. when try connect cloudera mysql database through sqoop. getting error -

"use --table or --query import"

i followed instruction described in sqoop documentation.

http://sqoop.apache.org/docs/1.4.6/sqoopuserguide.html#_connecting_to_a_database_server

is there anyway connect mysql server sqoop other using import statement.

[cloudera@quickstart ~]$ sqoop import --connect \ > jdbc:mysql://quickstart.cloudera/retail_db \ > --username cloudera --password cloudera warning: /usr/lib/sqoop/../accumulo not exist! accumulo imports fail. please set $accumulo_home root of accumulo installation. 16/07/28 07:07:31 info sqoop.sqoop: running sqoop version: 1.4.6-cdh5.5.0 16/07/28 07:07:31 warn tool.basesqooptool: setting password on command-line insecure. consider using -p instead. --table or --query required import. (or use sqoop import-all-tables.)

sqoop import used import data rdbms hdfs. import data need tell name of table or sql query. that's why getting error:

"use --table or --query import"

you want check if connection successful sqoop , don't want import data. can try other sqoop features

  • list databases

    sqoop list-databases --connect jdbc:mysql://database.example.com/ -username user --password pass

  • list tables in database

    sqoop list-tables --connect jdbc:mysql://database.example.com/testdb --username user --password pass
