Raghu Angadi commented on HADOOP-2907:
--------------------------------------
The ProcessBuilder getting stuck is also mostly caused by DataNode running out
of memory, because both the datanodes have "Exception in thread "process
reaper" java.lang.OutOfMemoryError: Java heap space". "process reaper" looks
like a thread in Java Process implementation. So I guess running out memory is
the main issue.
> dead datanodes because of OutOfMemoryError
