Harsh J commented on HDFS-3912: ------------------------------- bq. FYI: This patch is missing the branch-2 patch. After applying HDFS-3703 for branch-2, it's missing the DFS_NAMENODE_CHECK_STALE_DATANODE_DEFAULT settings, etc.. The diff may be dependent on the JIRA you mention, but perhaps not the patch itself. We merged the trunk commit directly into branch-2, as viewable/downloadable here: view at http://svn.apache.org/viewvc?view=revision&revision=1397219 and download at http://svn.apache.org/viewvc/hadoop/common/branches/branch-2/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/DFSConfigKeys.java?revision=1397219&view=co If you use git locally, you can also add a remote and cherry-pick it out I guess. > Detecting and avoiding stale datanodes for writing > -------------------------------------------------- > > Key: HDFS-3912 > URL: https://issues.apache.org/jira/browse/HDFS-3912 > Project: Hadoop HDFS > Issue Type: Sub-task > Affects Versions: 3.0.0 > Reporter: Jing Zhao > Assignee: Jing Zhao > Fix For: 1.2.0, 2.0.3-alpha > > Attachments: HDFS-3912.001.patch, HDFS-3912.002.patch, > HDFS-3912.003.patch, HDFS-3912.004.patch, HDFS-3912.005.patch, > HDFS-3912.006.patch, HDFS-3912.007.patch, HDFS-3912.008.patch, > HDFS-3912.009.patch, HDFS-3912-010.patch, HDFS-3912-branch-1.1-001.patch, > HDFS-3912-branch-1.patch, HDFS-3912.branch-1.patch > > > 1.
