Subject [jira] [Commented] (SQOOP-2554) Sqoop2: Enforce the element column in FromJobConfig of JDBC connector is a comma separated list
Date Tue, 08 Sep 2015 10:34:45 GMT

    [ https://issues.apache.org/jira/browse/SQOOP-2554?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14734587#comment-14734587

Jarek Jarcec Cecho commented on SQOOP-2554:
-------------------------------------------

This is a tricky one. I've seen users having whitespace and other special characters in the
column names which would break after applying this patch. I think that the proper solution
to this problem is to introduce a new Configuration type for {{List<String>}} similarly
as we have for {{Map<String, String>}}. This way, user can specify each column name
separately and we don't have do any parsing and hence we wouldn't get any limitations. I've
seen this particular issue while working on SQOOP-2243 as well, but did not yet created a
JIRA for it. Would you agree that it's a better solution [~dian.fu]?

> We should enforce the column specified by user for JDBC connector is a comma separated
list, such as "column1, column2". Illegal inputs such as "column1 column2" should be denied.
