-----------------------------------
Assignee: Gwen Shapira
> Import not splitted when using --boundary-query
> -----------------------------------------------
>
> Key: SQOOP-1277
> URL: https://issues.apache.org/jira/browse/SQOOP-1277
> Project: Sqoop
> Issue Type: Bug
> Components: hive-integration
> Affects Versions: 1.4.4
> Environment: Amazon AWS
> Reporter: Porati Sébastien
> Assignee: Gwen Shapira
> Priority: Critical
>
> I try to import Mysql Data into a hive table. I would like to use a custom
> boundary query. Results : sqoop does not split the load into multiple query
> and the import takes too long time.
> My creation command :
> {code:none}
> sqoop job -Dsqoop.metastore.client.record.password=true \
> --create importJobName -- import \
> --connect jdbc:mysql://some_jdbc_pram \
> --username user_name \
> --password MyPassword \
> --table my_table \
> --columns "collect_id,collected_data_id,value" \
> --boundary-query "SELECT min_value, max_value FROM sqoop_boundaries WHERE
> key_name = 'key.name'" \
> --split-by column_name \
> --num-mappers X \
> --hive-import \
> --hive-overwrite \
> --hive-table hivedb.hibetable --as-textfile --null-string \\\\N
> --null-non-string \\\\N
> {code}

> The following message is displayed :
> {code:none}
> WARN db.DataDrivenDBInputFormat: Could not find $CONDITIONS token in query:
> SELECT min_value, max_value FROM sqoop_boundaries WHERE key_name =
> 'key.name'; splits may not partition data.
> {code}
> I tried to add the $CONDITION to the creation command
> {code:none}
> --boundary-query "SELECT min_value, max_value FROM sqoop_boundaries WHERE
> key_name = 'key.name' AND \$CONDITION" \
> {code}
> But the job execution failed:
> {code:none}
