Change to PrimitiveKeyOpenHashMap broke Spark core build

[Ankur Dave]

Running sbt/sbt doc gives the following error:

[error] /Users/ankurdave/repos/graphx/core/src/main/scala/org/apache/spark/storage/ShuffleBlockManager.scala:172: not enough arguments for constructor PrimitiveKeyOpenHashMap: (initialCapacity: Int)(implicit evidence$3: ClassManifest[Int], implicit evidence$4: ClassManifest[Int])org.apache.spark.util.collection.PrimitiveKeyOpenHashMap[Int,Int]

The PrimitiveKeyOpenHashMap constructor has a default value for its only argument, but it doesn't seem to be working. Modifying the call site to pass the default argument explicitly fixes the problem.

Same here, was able to build only after specifying the default value.
