Issue description
After executing the tasks of a job, NodeExecutionManagerImpl does not clean up its dataProvider attribute, which then occupies memory for no reason, at least until the next job arrives.
Steps to reproduce this issue
  • Run the matrix multiplication sample, with a sufficiently large matrix (1000*1000 is ok) and a single node
  • Perform a GC on the node from the admin console
  • Take a heap dump of the node using the admin console
  • ==> the heap dump analysis with Eclipse MAT shows that almost all the memory is taken by a Matrix object, which is in fact sent to the node with the DataProvider
