Jim Kellerman commented on HADOOP-1045:
---------------------------------------

TODO: implement some kind of block caching in HRegion. While the DFS isn't hitting the disk to fetch blocks, HRegion is making IPC calls to DFS (via MapFile). This causes random reads to be *very* slow if you do a lot of them.
