Some logical issues need to address.
------------------------------------
Key: HDFS-1611
URL: https://issues.apache.org/jira/browse/HDFS-1611
Project: Hadoop HDFS
Issue Type: Bug
Components: hdfs client, name-node
Affects Versions: 0.20.2, 0.20.1
Reporter: Uma Maheswara Rao G
Priority: Minor
Title: Some code level logical issues.
Description:
1. DFSClient:
Consider the below case, if we enable only info, then below log will never be
logged.
if (ClientDatanodeProtocol.LOG.isDebugEnabled()) {
ClientDatanodeProtocol.LOG.info("ClientDatanodeProtocol addr=" + addr);
}
2.org.apache.hadoop.hdfs.server.namenode.FSNamesystem.registerMBean()
catch (NotCompliantMBeanException e) {
e.printStackTrace();
}
We can avoid using stackTace(). Better to add log message.
3. In org.apache.hadoop.hdfs.server.namenode.FSImage
since SimpleDateFormat is not a thread safe, we can move that to local to
the method.
private static final SimpleDateFormat DATE_FORM =
new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
