Matt Foley commented on HDFS-1806:
----------------------------------
These failures are unrelated to the patch, which only modifies TestBlockReport.
> TestBlockReport.blockReport_08() and _09() are timing-dependent and likely to
> fail on fast servers

> Method waitForTempReplica() polls every 100ms during block replication,
> attempting to "catch" a datanode in the state of having a TEMPORARY replica.
> But examination of a current Hudson test failure log shows that the replica
> goes from "start" to "TEMPORARY" to "FINALIZED" in only 50ms, so of course
> the poll usually misses it.
