Kihwal Lee created HDFS-4233:
--------------------------------
Summary: NN keeps serving even after no journals started while
rolling edit
Key: HDFS-4233
URL: https://issues.apache.org/jira/browse/HDFS-4233
Project: Hadoop HDFS
Issue Type: Bug
Components: name-node
Affects Versions: 0.23.5
Reporter: Kihwal Lee
Priority: Critical
We've seen namenode keeps serving even after rollEditLog() failure. Instead of
taking a corrective action or regard this condition as FATAL, it keeps on
serving and modifying its file system state. No logs are written from this
point, so if the namenode is restarted, there will be data loss.
