[jira] [Updated] (SPARK-41246) When RddId exceeds Integer.Max_VALUE, RddId becomes negative
[ https://issues.apache.org/jira/browse/SPARK-41246?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Qiang Yang updated SPARK-41246:
-------------------------------
Description:
The incrementAndGet method of AtomicInteger keeps increasing. When AtomicInteger increases to 2147483647 (Integer. MAX_VALUE) and then adds one, the value of AtomicInteger will become negative - 2147483648 (Integer. MIN_VALUE).
This problem occurs in long running tasks, such as stream tasks.
When BlockManager generates BlockId, BlockId only supports positive rddid, so BlockId generation fails
object BlockId {
val RDD = "rdd_([0-9]+)_([0-9]+)".r
