Subject Question regarding HDFS Recovery
Date Wed, 20 May 2009 04:59:52 GMT
Hi all,

I have some question regarding the hdfs recovery mechanism.

I see that INodeFileUnderConstruction has a "targets" field that stores list
of datanodes which store its last block.
However, I don't see them being used at all except that
"internalReleaseLease" function uses the length of the datanode list.
Is there any other use of the "target" fields rather than checking its

Could anyone shed some light on this?
