Pete Wyckoff commented on HADOOP-4775:
--------------------------------------
Another thing occurred to me is that on a 4GB machine, how big is the default
memory allocation? 1GB? How big is the DFSClient buffer per file? if it is the
block size, then 8 concurrent reads blows away 1GB.
Was there any output in the syslog?
