                 Key: HDFS-1806
                 URL: https://issues.apache.org/jira/browse/HDFS-1806
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: data-node, name-node
    Affects Versions: 0.22.0
            Reporter: Matt Foley


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.
