Ferenc Szabo commented on SQOOP-3241:
-------------------------------------
As we discussed with [~vasas], the SqoopOpstions objects are modified
improperly (after init) in two places:
- the CodeGenTool
- the ImportTool
I will investigate the following:
- whether we can make the SqoopOptions class immutable (and create it with a
Builder)
- whether SqoopOptions.clone() is correct (it's already implemented and used in
the JobTool, but there are no tests)
> ImportAllTablesTool uses the same SqoopOptions object for every table import

> Key: SQOOP-3241
> URL: https://issues.apache.org/jira/browse/SQOOP-3241
> Project: Sqoop
> Issue Type: Bug
> Affects Versions: 1.4.6
> Reporter: Szabolcs Vasas
> Assignee: Ferenc Szabo
>
> ImportAllTablesTool queries the list of tables from the database and invokes
> ImportTool#importTable method for each table.
> The problem is that it passes the same SqoopOptions object in every
> invocation and since SqoopOptions is not immutable this can lead to issues.
> For example in case of Parquet imports the CodeGenTool#generateORM method
> modifies the className field of the SqoopOptions object which is then remains
> the same for all the subsequent table imports and can cause job failures.
> One solution could be to create a new SqoopOptions object with the same field
> values for every ImportTool#importTable invocation.
