Description

Currently when Replicator can not find datanodes to place required replications for a block, it does not print the actual block id. Block id would help while debugging problems similar to http://www.nabble.com/Under-replicated-block-doesn't-get-fixed-until-DFS-restart-td14624430.html , HADOOP-2201.

log from trunk currently looks like :

 2007-11-13 22:08:40,727 WARN  fs.FSNamesystem (ReplicationTargetChooser.java:chooseTarget(177)) -
    Not able to place enough replicas, still in need of 1
