Description
When upgrading from Hadoop 0.10.1 to 0.11.2, I see the number of racks and datanode double after the 2nd startup of the Namenode. After the 3rd startup, they correct themselves:
Namenode Log After 1st Startup:
2007-03-06 18:27:27,045 INFO org.apache.hadoop.dfs.StateChange: STATE* Network topology has 1 racks and 4 datanodes
Namenode Log After 2nd Startup:
2007-03-06 18:27:43,201 INFO org.apache.hadoop.dfs.StateChange: STATE* Network topology has 2 racks and 8 datanodes
Namenode Log After 3rd Startup:
2007-03-06 18:28:09,730 INFO org.apache.hadoop.dfs.StateChange: STATE* Network topology has 1 racks and 4 datanodes
