Work Description: amaliujia opened a new pull request #12122:
URL: https://github.com/apache/beam/pull/12122
Reverts apache/beam#12079
It turns out that on direct runner, NULL will not be passed to CombineFn
thus all NULL inputs are ignored. And then if there is any non-null inputs,
bit_and will be applied on them only, which leads to a non-null result, which
is not correct.
Before we can figure out the root cause and propose a fix, we should revert
this implementation.
