Konstantin Boudnik commented on HDFS-619:
-----------------------------------------

Sounds like the test case you have here relates to some of the scenarios described by some of testplan's BlockRecovery_02 cases. If so, would it make sense to sync the names of the test methods.
 
Also, it is quite possible that that we don't need that complex testing scenarios for Block recovery. I'm willing to reconsider this section of the test plan :-)

> In the [append design|https://issues.apache.org/jira/secure/attachment/12415768/appendDesign2.pdf], there is a block recovery algorithm presented in Section 6.5.  We are going to implement step 4a, datanode replica recovery initialization, in this issue.
