I thought data will be divided by 50% and 50% to both loaders. But actually the second loader does nothing, because its DataReader does not have any data to provide. Is it by design? > >> About loaders do not have data in a balanced way. > My scenario is 4 "jdbc_mysql" extractors to extract 100k row data (10MB). There are 2 Kite loaders to read data. > This must be a bug that needs to be fixed in SQOOP ( [~abec] confirmed it. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
