-----------------------------------
Fix Version/s: 2.0.0
> ToolRunner is not thread-safe
> -----------------------------
>
> Key: SQOOP-1300
> URL: https://issues.apache.org/jira/browse/SQOOP-1300
> Project: Sqoop
> Issue Type: Bug
> Components: tools
> Reporter: Ajay Chitre
> Priority: Critical
> Labels: tools
> Fix For: 2.0.0
>
>
> ToolRunner class is not thread-safe because it uses GenericOptionsParser.
> The constructor of GenericOptionsParser uses 'OptionBuilder' which is a
> singleton class that uses instance variables. In other words, OptionBuilder
> is NOT thread safe. As a result, when multiple Hadoop jobs are triggered
> simultaneously using ToolRunner they end up stepping on each other.
> The easiest way to fix it is by making 'buildGeneralOptions' synchronized in
> GenericOptionsParser.
> private static synchronized Options buildGeneralOptions(Options opts) {
> If this seems like a correct way of fixing this, either we can provide a
> patch or someone can quickly fix it. Thanks.
