----------------------------------------------

             Summary: dynamic configuration file renaming fails on Windows
                 Key: ZOOKEEPER-1835
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1835
             Project: ZooKeeper
          Issue Type: Bug
          Components: quorum
    Affects Versions: 3.5.0
         Environment: Windows 7 64-bit, Oracle Java  1.6.0_32-b05
            Reporter: Bruno Freudensprung


On Windows, reconfig fails to rename the tmp dynamic config file to the real dynamic config filename.
Javadoc of java.io.File.renameTo says the behavior is highly plateform dependent, so I guess this should not be a big surprise.
The problem occurs in src/java/main/org/apache/zookeeper/server/quorum/QuorumPeerConfig.java that could be modified like this:
+ curFile.delete();
if (!tmpFile.renameTo(curFile)) {
+ configFile.delete();
if (!tmpFile.renameTo(configFile)) {
As suggested by Alex in https://issues.apache.org/jira/browse/ZOOKEEPER-1691 (btw there is more information about my test scenario over there) it is a bit "scary" to delete the current configuration file.
