Sameer Paranjpye commented on HADOOP-3193:
------------------------------------------
I'd like to do more here. In addition to reporting corrupt blocks in the log,
the Namenode should try and determine *where* the corruption occured i.e. on
disk on the Datanode vs elsewhere (network transmission or in memory on the
client).
