They can still be donated to Impala with another Software Grant,
however you would need that both from Cloudera Inc. and Sergey Lyubka
(CTO of Cloudera) given the joint (c) at

(I guess this code predates Sergey's co-founding of the Cloudera corporation)

Somehow Cloudera's (c) is not noted in
and neither are listed in the top-level LICENSE - so that is what
needs sorting out.

Many ASF projects 'adapt' such free-hanging "bits and bobs code" under
their umbrella - sometimes such code can get a "new life" - that's
after all part of what open source is about.

If they are in a SG it means they would be covered by the ASF license.
But there should not be a big problem with them being mentioned in the
LICENSE file with the compatible MIT license - at least if it's likely
to be "dormant" code that won't evolve much under Apache. The only
effect is that some of the protections of the ASF license then won't
clearly apply - e.g. protection against patent litigation.

I guess the main principle is that the 'main' project code should be
covered by the software grant - having remnants from the same
copyright holder that is not part of the software grant should
understandably be a yellow flag.

I think as a project (with mentors help) Impala will have to review if
the code in question is "important enough" (e.g. contains a patented
algorithm, or is core to how Impala works) to pursue additional
Software Grant (or license change) from upstream or if it's just an
innocent embedded dependency that can be noted it in the top level
