---------------------------------
Summary: TransferFsImage.downloadEditsToStorage should use a tmp
file for destination
Key: HDFS-4300
URL: https://issues.apache.org/jira/browse/HDFS-4300
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 2.0.2-alpha
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Priority: Critical
Currently, in TransferFsImage.downloadEditsToStorage, we download the edits
file directly to its finalized path. So, if the transfer fails in the middle, a
half-written file is left and cannot be distinguished from a correct file. So,
future checkpoints by the 2NN will fail, since the file is truncated in the
middle -- but it won't ever download a good copy because it thinks it already
has the proper file.
