question about BlockLocation setHosts

[George Kousiouris]

Hi all,
I had a question regarding the setHosts method of the BlockLocation 
class in hadoop hdfs. Does this make the block in question to be moved 
to the specified host?

Furthermore, where does the getHosts method of block location get the 
host names? It does not seem to utilize the rack aware setup names.

Thanks,
George
