Description:
I am using Hadoop-2.10.0.
The configuration parameter `dfs.namenode.audit.loggers` allows `default`
(which is the default value) and
`org.apache.hadoop.hdfs.server.namenode.top.TopAuditLogger`.
When I use `org.apache.hadoop.hdfs.server.namenode.top.TopAuditLogger`,
namenode will not be started successfully because of an
`InstantiationException` thrown from
`org.apache.hadoop.hdfs.server.namenode.FSNamesystem.initAuditLoggers`.
The root cause is that while initializing namenode, `initAuditLoggers` will be
called and it will try to call the default constructor of
`org.apache.hadoop.hdfs.server.namenode.top.TopAuditLogger` which doesn't have
a default constructor. Thus the `InstantiationException` exception is thrown.

*Detailed Root Cause*
There is no default constructor in
`org.apache.hadoop.hdfs.server.namenode.top.TopAuditLogger`:
{code:java}
/**
* An {@link AuditLogger} that sends logged data directly to the metrics
* systems. It is used when the top service is used directly by the name node
*/
@InterfaceAudience.Private
public class TopAuditLogger implements AuditLogger {
public static finalLogger LOG =
LoggerFactory.getLogger(TopAuditLogger.class);
private final TopMetrics topMetrics;
public TopAuditLogger(TopMetrics topMetrics) {
Preconditions.checkNotNull(topMetrics, "Cannot init with a null " +
"TopMetrics");
this.topMetrics = topMetrics;
}
@Override
public void initialize(Configuration conf) {
}
{code}
As long as the configuration parameter `dfs.namenode.audit.loggers` is set to
`org.apache.hadoop.hdfs.server.namenode.top.TopAuditLogger`, `initAuditLoggers`
will try to call its default constructor to make a new instance:
{code:java}
private List initAuditLoggers(Configuration conf) {
// Initialize the custom access loggers if configured.
Collection alClasses =
conf.getTrimmedStringCollection(DFS_NAMENODE_AUDIT_LOGGERS_KEY);
List auditLoggers = Lists.newArrayList();
if (alClasses != null && !alClasses.isEmpty()) {
for (String className : alClasses) {
try {
AuditLogger logger;
if (DFS_NAMENODE_DEFAULT_AUDIT_LOGGER_NAME.equals(className)) {
logger = new DefaultAuditLogger();
} else {
logger = (AuditLogger) Class.forName(className).newInstance();
}
logger.initialize(conf);
auditLoggers.add(logger);
} catch (RuntimeException re) {
throw re;
} catch (Exception e) {
throw new RuntimeException(e);
}
}
}
{code}
`initAuditLoggers` tries to call the default constructor to make a new instance
in:
{code:java}
logger = (AuditLogger) Class.forName(className).newInstance();
{code}
This is very different from the default configuration, `default`, which
implements a default constructor so the default is fine.
*How To Reproduce*

# Set the value of configuration parameter `dfs.namenode.audit.loggers` to
`org.apache.hadoop.hdfs.server.namenode.top.TopAuditLogger` in

# The namenode will not be started successfully.

There is no default constructor in

As long as the configuration parameter `dfs.namenode.audit.loggers` is set to

will try to call its default constructor to make a new instance:
{code:java}

Description:
I am using Hadoop-2.10.0.
The configuration parameter `dfs.namenode.audit.loggers` allows `default`
(which is the default value) and
`org.apache.hadoop.hdfs.server.namenode.top.TopAuditLogger`.
When I use `org.apache.hadoop.hdfs.server.namenode.top.TopAuditLogger`,
namenode will not be started successfully because of an
`InstantiationException` thrown from
`org.apache.hadoop.hdfs.server.namenode.FSNamesystem.initAuditLoggers`.
The root cause is that while initializing namenode, `initAuditLoggers` will be
called and it will try to call the default constructor of
`org.apache.hadoop.hdfs.server.namenode.top.TopAuditLogger` which doesn't have
a default constructor. Thus the `InstantiationException` exception is thrown.

*Detailed Root Cause*
There is no default constructor in
`org.apache.hadoop.hdfs.server.namenode.top.TopAuditLogger`:
{code:java}
/**
* An {@link AuditLogger} that sends logged data directly to the metrics
* systems. It is used when the top service is used directly by the name node
*/
@InterfaceAudience.Private
public class TopAuditLogger implements AuditLogger {
public static finalLogger LOG =
LoggerFactory.getLogger(TopAuditLogger.class);
private final TopMetrics topMetrics;
public TopAuditLogger(TopMetrics topMetrics) {
Preconditions.checkNotNull(topMetrics, "Cannot init with a null " +
"TopMetrics");
this.topMetrics = topMetrics;
}
@Override
public void initialize(Configuration conf) {
}
{code}
As long as the configuration parameter `dfs.namenode.audit.loggers` is set to
`org.apache.hadoop.hdfs.server.namenode.top.TopAuditLogger`, `initAuditLoggers`
will try to call its default constructor to make a new instance:
{code:java}
private List initAuditLoggers(Configuration conf) {
// Initialize the custom access loggers if configured.
Collection alClasses =
conf.getTrimmedStringCollection(DFS_NAMENODE_AUDIT_LOGGERS_KEY);
List auditLoggers = Lists.newArrayList();
if (alClasses != null && !alClasses.isEmpty()) {
for (String className : alClasses) {
try {
AuditLogger logger;
if (DFS_NAMENODE_DEFAULT_AUDIT_LOGGER_NAME.equals(className)) {
logger = new DefaultAuditLogger();
} else {
logger = (AuditLogger) Class.forName(className).newInstance();
}
logger.initialize(conf);
auditLoggers.add(logger);
} catch (RuntimeException re) {
throw re;
} catch (Exception e) {
throw new RuntimeException(e);
}
}
}
{code}
`initAuditLoggers` tries to call the default constructor to make a new instance
in:
{code:java}
logger = (AuditLogger) Class.forName(className).newInstance();
{code}
This is very different from the default configuration, `default`, which
implements a default constructor so the default is fine.
