Work Description: tvalentyn commented on pull request #14607:
URL: https://github.com/apache/beam/pull/14607#issuecomment-833843012
> To clarify why this came up: we have some test that takes the pipeline
options and tries to turn them back into cmdline args and then read them again.
>
> So `null` gets serialized to the string `"null"` but I don't think this
can be expressed in cmdline args. The translation wasn't that smart, so it put
`--resourceHints=null` on the command line, and then that parses back as the
JSON value `["null"]`. That's the real bug. But as long as we don't need null
vs empty list, let's just do empty list.
@TheNeuralBit also came across this and beat me to the fix:

> As discussed in BEAM-673 runners can allocate workers to accomplish their
> work in a better way if they can take into account some hints from the
> transforms, e.g. a source can hint data locality and with this information
> the runner can allocate the workers in an better way, this can also be the
> case with a particular transform that can suggest to the runner to be
> executed in a worker with a specific resource, e.g. GPU.
