Hi, Upon launching the Namenode and Datanodes, I seem to be getting the following error messages (on freshly checkedout and built code) at a datanode:
* (In the /mnt/hadoop/logs/hadoop-root-datanode-*.log file ) * * ########################################################################################### * *2011-04-20 02:40:35,875 WARN org.apache.hadoop.hdfs.server.datanode.DataNode: java.io.IOException: java.lang.NumberFormatException: For input string: "dfs.heartbeat.interval"* * at java.lang.NumberFormatException.forInputString(NumberFormatException.java:48) * * at java.lang.Long.parseLong(Long.java:403)* * at java.lang.Long.parseLong(Long.java:461)* * at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.handleHeartbeat(FSNamesystem.java:2811) * * at org.apache.hadoop.hdfs.server.namenode.NameNode.sendHeartbeat(NameNode.java:1274) * * at sun.reflect.GeneratedMethodAccessor4.invoke(Unknown Source)* * at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) * * at java.lang.reflect.Method.invoke(Method.java:597)* * at org.apache.hadoop.ipc.WritableRpcEngine$Server.call(WritableRpcEngine.java:357) * * at org.apache.hadoop.ipc.Server$Handler$1.run(Server.java:1412)* * at org.apache.hadoop.ipc.Server$Handler$1.run(Server.java:1408)* * at java.security.AccessController.doPrivileged(Native Method)* * at javax.security.auth.Subject.doAs(Subject.java:396)* * at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1142) * * at org.apache.hadoop.ipc.Server$Handler.run(Server.java:1406)* * * * at org.apache.hadoop.ipc.Client.call(Client.java:1028)* * at org.apache.hadoop.ipc.WritableRpcEngine$Invoker.invoke(WritableRpcEngine.java:197) * * at $Proxy4.sendHeartbeat(Unknown Source)* * at org.apache.hadoop.hdfs.server.datanode.DataNode.offerService(DataNode.java:933) * * at org.apache.hadoop.hdfs.server.datanode.DataNode.run(DataNode.java:1485) * * at java.lang.Thread.run(Thread.java:619)* * ########################################################################################### * Is this related any recent commits?
