+ Apache Kudu (incubating) is an effort undergoing incubation at the Apache Software
+ Foundation (ASF), sponsored by the Apache Incubator PMC. Incubation is
+ required of all newly accepted projects until a further review
+ indicates that the infrastructure, communications, and decision making
+ process have stabilized in a manner consistent with other successful
+ ASF projects. While incubation status is not necessarily a reflection
+ of the completeness or stability of the code, it does indicate that the
+ project has yet to be fully endorsed by the ASF.
