Ted Yu created KYLIN-3588: ----------------------------- Summary: Potentially duplicate put to RemoveBlackoutRealizationsRule#filters map Key: KYLIN-3588 URL: https://issues.apache.org/jira/browse/KYLIN-3588 Project: Kylin Issue Type: Bug Reporter: Ted Yu
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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
