I believed you made thing overly complicated. You only have one hash table,
and try to remove the entries that has remove_ of it. Not sure why you need
to use reduce and map. You can use `each` to go through first key of the
hash table, then use filter to filter out unwanted keys like,
# this class is use to setup owner and group
class reduce_test {
$hash = {
attribute1 => 1,
attribute2 => 2,
attribute3 => 3,
remove1 => 4,
remove2 => 5,
attribute4 => 6,
attribute5 => 7,
}
notice("hash table => ${hash}")
$h = $hash.filter | $items | {
$items[0] !~ /^remove/
}
notice("hash table after filtering out 'remove*' key = ${h}")
}
For the each part, I will left for you to figure out.
