> Key: KYLIN-3588
> URL: https://issues.apache.org/jira/browse/KYLIN-3588
> Project: Kylin
> Issue Type: Bug
> Reporter: Ted Yu
> Assignee: jiatao.tao
> Priority: Minor
>
> Here is related code:
> {code}
> IRealizationFilter filter = filters.get(conf);
> if (filter == null) {
> try {
> Class<? extends IRealizationFilter> clz = ClassUtil.forName(conf.getQueryRealizationFilter(), IRealizationFilter.class);
> filter = clz.getConstructor(KylinConfig.class).newInstance(conf);
> } catch (Exception e) {
> throw new RuntimeException(e);
> }
> filters.put(conf, filter);
> {code}
> Two threads may find out there is no filter for conf, they would proceed with creation of IRealizationFilter instances and try to put into the map.
