Summary: Remove confusing log output in
FsDatasetImpl#getInitialVolumeFailureInfos
Key: HDFS-11147
URL: https://issues.apache.org/jira/browse/HDFS-11147
Project: Hadoop HDFS
Issue Type: Improvement
Components: datanode
Reporter: Chen Liang
Assignee: Chen Liang
Priority: Minor
In {{FsDatasetImpl}} the method {{getInitialVolumeFailureInfos}} there is
{code}
for (StorageLocation sl: dataLocations) {
LOG.info("Adding to failedLocationSet " + sl);
failedLocationSet.add(sl);
}
for (Iterator<Storage.StorageDirectory> it = storage.dirIterator();
it.hasNext(); ) {
Storage.StorageDirectory sd = it.next();
failedLocationSet.remove(sd.getStorageLocation());
LOG.info("Removing from failedLocationSet " + sd.getStorageLocation());
}
}
{code}
The log messages here can be confusing as it may prints "Adding to
failedLocationSet" message, which looks like a failure is happening, but later
on removed the storage location from failedLocationSet. We should just remove
these two log messages.
