Thanks Eli for the list. I have merged the bugs you identified to 0.23. I am in the process of merging HA change. I have several conflicts, stemming from the changes that are no in 0.23. Pushing following jiras to 0.23 will make the merge easier. I believe these are mostly straight forward changes:
HADOOP-7557 Make IPC header be extensible HDFS-3003. Remove getHostPortString() from NameNode, replace it with NetUtils.getHostPortString(). HADOOP-8108. Move method getHostPortString() from NameNode to NetUtils. HDFS-2764. TestBackupNode is racy. HDFS-2430. The number of failed or low-resource volumes the NN can tolerate should be configurable. HADOOP-7358. Improve log levels when exceptions caught in RPC handler. HDFS-2410. Further cleanup of hardcoded configuration keys and values. HDFS-2285. BackupNode should reject requests to modify namespace. HADOOP-7729. Send back valid HTTP response if user hits IPC port with HTTP GET. HADOOP-7717. Move handling of concurrent client fail-overs to RetryInvocationHandler If no one gets back to me in a day, I will start merging these to 0.23.
