----------------------------------------
Summary: Improve escaping of column specified in the --split-by
parameter
Key: SQOOP-898
URL: https://issues.apache.org/jira/browse/SQOOP-898
Project: Sqoop
Issue Type: Improvement
Affects Versions: 1.4.2
Reporter: Jarek Jarcec Cecho
Assignee: Jarek Jarcec Cecho
Oracle database is using double quotes (") to escape column names. The same
escape character is also used in Sqoop and Hadoop on several places with make
it really hard to guess the correct escaping. For example when I wanted to
split data by column {{id}} (lower cased), I needed to escape it three times to
{{"""id"""}} to get boundary query generated with {{...min("id")...}}. The job
with three times escaped split by column then subsequently failed on different
place. I think that we should improve that.
