Summary: FsDatasetImpl#removeVolumes floods the logs when removing
the volume
Key: HDFS-12107
URL: https://issues.apache.org/jira/browse/HDFS-12107
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Haohui Mai
Assignee: Haohui Mai
FsDatasetImpl#removeVolumes() prints all block ids on a volume when removing
it, which floods the log of DN.
{noformat}
for (String bpid : volumeMap.getBlockPoolList()) {
List<ReplicaInfo> blocks = new ArrayList<>();
for (Iterator<ReplicaInfo> it =
volumeMap.replicas(bpid).iterator(); it.hasNext();) {
ReplicaInfo block = it.next();
final StorageLocation blockStorageLocation =
block.getVolume().getStorageLocation();
LOG.info("checking for block " + block.getBlockId() +
" with storageLocation " + blockStorageLocation);
if (blockStorageLocation.equals(sdLocation)) {
blocks.add(block);
it.remove();
}
}
{noformat}
The logging level should be {{DEBUG}} or {{TRACE}} instead of {{INFO}}.
