I am using Flink for streaming the data which is in the csv file. I want to put it into table format with certain schema. For this purpose I am using Flink-table\_2.10-1.1.3.jar (Table api) but I got the errors:

```
log4j:WARN No appenders could be found for logger (org.apache.flink.api.java.typeutils.TypeExtractor).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

When I explore the corresponding jar, the respective class is present there. Can you please tell that why this is happening? 

Also can I get the maven source so that I can build the Flink-table .jar at my place?
