I also propose following jiras, which are non append related bug fixes from 0.20-append branch:
- HDFS-1164. TestHdfsProxy is failing. - HDFS-1211. Block receiver should not log "rewind" packets at INFO level. - HDFS-1118. Fix socketleak on DFSClient. - HDFS-1210. DFSClient should log exception when block recovery fails. - HDFS-606. Fix ConcurrentModificationException in invalidateCorruptReplicas. - HDFS-561. Fix write pipeline READ_TIMEOUT. - HDFS-1202. DataBlockScanner throws NPE when updated before initialized. Risk Level: These are useful bugfixes from append branch and are not big changes to the code base. These jiras have already been merged into 0.20-security branch.
