Bogdan Raducanu updated SPARK-20280:
------------------------------------
Description:
in FileStatusCache.scala:
{code}
.weigher(new Weigher[(ClientId, Path), Array[FileStatus]] {
override def weigh(key: (ClientId, Path), value: Array[FileStatus]): Int
= {
(SizeEstimator.estimate(key) + SizeEstimator.estimate(value)).toInt
}})
{code}
Weigher.weigh returns Int but the size of an Array[FileStatus] could be bigger
than Int.maxValue. Then, a negative value is returned, leading to this
exception:
{code}
* [info] java.lang.IllegalStateException: Weights must be non-negative
* [info] at
com.google.common.base.Preconditions.checkState(Preconditions.java:149)
* [info] at
