     [exec]                         Please justify why no new tests are needed for this patch.
     [exec]                         Also please list what manual steps were performed to verify
this patch.
     [exec] 
     [exec]     +1 javadoc.  The javadoc tool did not generate any warning messages.
     [exec] 
     [exec]     +1 javac.  The applied patch does not increase the total number of javac compiler
warnings.
     [exec] 
     [exec]     +1 findbugs.  The patch does not introduce any new Findbugs warnings.
     [exec] 
     [exec]     +1 release audit.  The applied patch does not increase the total number of

     [exec] 
     [exec]     +1 system tests framework.  The patch passed system tests framework compile.

Tests are not added because the existing datanode updgrade/finalize related tests test this
change.

requires block pool ID information. Datanode uses this to finalize only the storage associated
with the block pool.
