Can you point me to the jira where that decision was made?
Hadoop globbing only covers a small subset of all use cases. For example
for timeseries analysis i need to select partitions for a set of days that can
not be expressed as a glob. I could consider a union of dataframes, but i am
not sure if in that case predicates pushdown will work as expected. It might be
have some performance overhead. I will investigate.
Also as far as i know hadoop input formats will not support commas in
filenames either, so whats the point of supporting it if it doesnt work? Just
curious
