Disclaimer
----------------
Apache Tajo 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.
