-------------------------------------
Summary: Upgrade RoaringBitmap to 0.9.22
Key: SPARK-37025
URL: https://issues.apache.org/jira/browse/SPARK-37025
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 2.0.0, 2.1.0, 2.2.0, 2.3.3, 2.4.0, 3.0.0
Reporter: Igor Dvorzhak
Assignee: Lantao Jin
Fix For: 2.3.4, 2.4.2, 3.0.0
HighlyCompressedMapStatus uses RoaringBitmap to record the empty blocks. But
RoaringBitmap-0.5.11 couldn't be ser/deser with unsafe KryoSerializer.
We can use below UT to reproduce:
{code}
test("kryo serialization with RoaringBitmap") {
val bitmap = new RoaringBitmap
bitmap.add(1787)
val safeSer = new KryoSerializer(conf).newInstance()
val bitmap2 : RoaringBitmap = safeSer.deserialize(safeSer.serialize(bitmap))
assert(bitmap2.equals(bitmap))
conf.set("spark.kryo.unsafe", "true")
val unsafeSer = new KryoSerializer(conf).newInstance()
val bitmap3 : RoaringBitmap =
unsafeSer.deserialize(unsafeSer.serialize(bitmap))
assert(bitmap3.equals(bitmap)) // this will fail
}
{code}
Upgrade to latest version 0.7.45 to fix it
