[jira] [Updated] (SPARK-37025) Upgrade RoaringBitmap to 0.9.22

     [ https://issues.apache.org/jira/browse/SPARK-37025?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Igor Dvorzhak updated SPARK-37025:
----------------------------------
        Fix Version/s:     (was: 2.4.2)
                           (was: 2.3.4)
                           (was: 3.0.0)
    Affects Version/s:     (was: 2.3.3)
                           (was: 2.4.0)
                           (was: 3.0.0)
                           (was: 2.2.0)
                           (was: 2.1.0)
                           (was: 2.0.0)
                       3.2.0
          Description:     (was: 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)
