Description

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.
