-------------------------------------------------------------
Key: HADOOP-3337
URL: https://issues.apache.org/jira/browse/HADOOP-3337
Project: Hadoop Core
Issue Type: Bug
Affects Versions: 0.18.0
Reporter: Konstantin Shvachko
Assignee: Tsz Wo (Nicholas), SZE
Priority: Blocker
Fix For: 0.18.0
HADOOP-3283 introduced a new field ipcPort in DatanodeInfo, which was not
reflected in the reading/writing file system image files.
Particularly, reading edits generated by the previous version of hadoop throws
the following exception:
{code}
