------------------------------------
Summary: Creating a replicated file in a EC zone does not
correctly serialized in EditLogs
Key: HDFS-12840
URL: https://issues.apache.org/jira/browse/HDFS-12840
Project: Hadoop HDFS
Issue Type: Bug
Components: erasure-coding
Affects Versions: 3.0.0-beta1
Reporter: Lei (Eddy) Xu
Assignee: Lei (Eddy) Xu
Priority: Blocker
When create a replicated file in an existing EC zone, the edit logs does not
differentiate it from an EC file. When {{FSEditLogLoader}} to replay edits,
this file is treated as EC file, as a results, it crashes the NN because the
blocks of this file are replicated, which does not match with {{INode}}.
