Sqoop is what you are looking for ! I'm using it to send my data into MySQL. The only trick is that you must use TEXTFILE without partitions from <pre><code>file_format: : SEQUENCEFILE | TEXTFILE | RCFILE (Note: only available starting with 0.6.0) | ORC (Note: only available starting with 0.11.0) | INPUTFORMAT input_format_classname OUTPUTFORMAT output_format_classname </code></pre> <a href="https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-Create%2FDrop%2FTruncateTable" rel="nofollow">https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-Create%2FDrop%2FTruncateTable</a> If it's not in TEXTFILE, you can do a <blockquote> INSERT INTO TABLE tablename1 [PARTITION (partcol1=val1, partcol2=val2 ...)] select_statement1 FROM from_statement; </blockquote> <a href="https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DML#LanguageManualDML-InsertingdataintoHiveTablesfromqueries" rel="nofollow">https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DML#LanguageManualDML-InsertingdataintoHiveTablesfromqueries</a> Now that you have your export table, you may use sqoop as follow: <pre><code>sqoop export --connect ${YOUR_CONNECTION_STRING} --username ${YOUR_USERNAME} --password ${YOUR_PASSWORD} --table ${MYSQL_TABLE_NAME} --update-key ${FIELD1[,FIELD2]*} --update-mode allowinsert --export-dir ${PATH_TO_YOUR_HIVE_TABLE_ON_HDFS} --input-fields-terminated-by \001 --num-mappers 1 --batch --verbose </code></pre> <a href="http://sqoop.apache.org/docs/1.4.4/SqoopUserGuide.html#_syntax_3" rel="nofollow">http://sqoop.apache.org/docs/1.4.4/SqoopUserGuide.html#_syntax_3</a> Good luck !

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
