David Karoly created SQOOP-2995:
-----------------------------------
Summary: ackward incompatibility introduced by Custom Tool options
Key: SQOOP-2995
URL: https://issues.apache.org/jira/browse/SQOOP-2995
Project: Sqoop
Issue Type: Bug
Reporter: David Karoly
SQOOP-2333 adds support for custom options for User Defined Plugins using
property customtool.options.jsonmap
When this is used in combination with sqoop metastore we get backward
incompatible behavior:
* if a job is created in a previous sqoop version not containing SQOOP-2333,
the job definition won't contain customtool.options.jsonmap
* since SQOOP-2333 introduced this is a mandatory property and we get an
exception if customtool.options.jsonmap is not present
* therefore 'job -show' or 'job -exec' will fail for any jobs created in
previous versions not containing SQOOP-2333
Sqoop should initialize its internal map object (which is restored from the
'customtool.options.jsonmap' metastore property) to an empty map instead of
null even if the 'customtool.options.jsonmap' property is not present in the
metastore database.
