> This jira adds the following 2 features to src/test
> 1) it extends DataNodeCluster to allow blocks to be injected for simulted
> data nodes.
> 2) a new command, CreatedEditsLog which creates an NN image edits logs that
> has a transactions for new files. The edits log file can be copied to the
> NN's image.
> Using the two in conjunction one can inject a set of blocks in a NN and in a
> set of Datanodes and use it for testing, for example a cluster of 3K DNs
