---------------------------------
Summary: DataNode exclusion log message should be a warning
Key: HDFS-10381
URL: https://issues.apache.org/jira/browse/HDFS-10381
Project: Hadoop HDFS
Issue Type: Bug
Components: datanode
Affects Versions: 2.6.0
Reporter: John Zhuge
Assignee: John Zhuge
Priority: Minor
When adding a DN to {{excludedNodes}}, it should log a warning message instead
of info.
{code}
success = createBlockOutputStream(nodes, storageTypes, 0L, false);
if (!success) {
LOG.info("Abandoning " + block);
dfsClient.namenode.abandonBlock(block, stat.getFileId(), src,
dfsClient.clientName);
block = null;
final DatanodeInfo badNode = nodes[errorState.getBadNodeIndex()];
LOG.info("Excluding datanode " + badNode);
excludedNodes.put(badNode, badNode);
}
{code}
