Apache Impala (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.
