Astyanax. How to read SET and MAP Datatypes in cassandra

Question

I am trying to read a column of type Set from cassandra using the following astyanax code.

val genres = col.getColumnByName("genres")
val genValue = genres.getValue(new SetSerializer[String](UTF8Type.instance))

I found similar code in Astyanax documentation as well

https://github.com/Netflix/astyanax/wiki/Collections

but I get error

org.apache.cassandra.serializers.MarshalException: Unexpected extraneous bytes after set value
    at org.apache.cassandra.serializers.SetSerializer.deserialize(SetSerializer.java:64)
    at org.apache.cassandra.serializers.SetSerializer.deserialize(SetSerializer.java:27)
    at org.apache.cassandra.db.marshal.AbstractType.compose(AbstractType.java:142)
    at com.netflix.astyanax.serializers.SetSerializer.fromByteBuffer(SetSerializer.java:32)

My table definition is

CREATE TABLE movielens_small.movies (
    id uuid PRIMARY KEY,
    avg_rating float,
    genres set<text>,
    name text,
    release_date date,
    url text,
    video_release_date date
) WITH bloom_filter_fp_chance = 0.01

I can easily to a select query in cqlsh. so I don't think there is some problem with db.

Edit:: I also tried

val myset = ListType.getInstance(UTF8Type.instance)
val genValue = myset.compose(genres.getByteBufferValue) 

But it throws the same error that there are unexpected extraneous bytes.

Edit2:: I also tried

val genValue = new String(genres.getByteBufferValue.array(), "UTF-8")

This doesn't throw an error, and I can see data... but its like gibberish.

Edit3:: I also tried

val setSer = new SetSerializer[String](UTF8Type.instance)
val buf = genres.getByteBufferValue
val genValue = setSer.fromByteBuffer(buf)
println(s"${name.getStringValue} rating: ${avgRating.getFloatValue} genres: ${genValue}")

But again the same problem of org.apache.cassandra.serializers.MarshalException: Unexpected extraneous bytes after set value
