Ivan Kelly commented on HDFS-2003:
----------------------------------
Fixed the reading of blocks so that replication is adjusted before use. While
it may not be strictly necessary, it's could introduce a real bug in the
future, so its best to set the replication correctly from the outset.
https://issues.apache.org/jira/secure/attachment/12481812/HDFS-2003.diff is the
same as http://issues.apache.org/jira/secure/attachment/12481764/hdfs-2003.txt
with HDFS-2003-replicationfix-delta.diff applied.
> Separate FSEditLog reading logic from editLog memory state building logic

> Currently FSEditLogLoader has code for reading from an InputStream
> interleaved with code which updates the FSNameSystem and FSDirectory. This
> makes it difficult to read an edit log without having a whole load of other
> object initialised, which is problematic if you want to do things like count
> how many transactions are in a file etc.
> This patch separates the reading of the stream and the building of the memory
> state.
