WSO2 DAS 3.0.0 with API Manager 1.9.0 not working - oracle

Question

I am using trying to use DAS 3.0.0 as replacement of BAM with WSO2 API Manager 1.9.0/1.9.1 with Oracle for WSO2AM_STATS_DB.
I am following http://blog.rukspot.com/2015/09/publishing-apim-runtime-statistics-to.html
I can see data in DAS's carbon dashboard in Data Explorer tables ORG_WSO2_APIMGT_STATISTICS_REQUEST and ORG_WSO2_APIMGT_STATISTICS_RESPONSE.
But data is not stored in Oracle. Therefore I am not able to see Statistics in publisher of AM. It keeps saying "Data publishing is enabled. Generate some traffic to see statistics."
I am getting following error in log:
[2015-12-08 13:00:00,022] INFO {org.wso2.carbon.analytics.spark.core.AnalyticsT
ask} - Executing the schedule task for: APIM_STAT_script for tenant id: -1234

Am I missing something?
Can anyone please help me to figure out this issue?
Thanks in advance.

Move all the libraries(jars) into your project's /WEB-INF/lib. Now all the libraries/jars under /WEB-INF/lib will come under classpath.
use snappy-java jar file and it will work as you want.
