Hi .
  Sorry to bother you againt.

  I need to close this question  by myself.
  Here is my core-site.xml:
  ******************************************************************
  <configuration>
   <property>
   <name>fs.default.name</name>
   <value>hdfs://Hadoop01:8020</value>
  </property>
 </configuration>
  ******************************************************************
 my hdfs-site.xml:
 *********************************************************************
<configuration>
    <property>
       <name>dfs.nameservices</name>
       <value>ns1,ns2</value>
   </property>
   <property>
       <name>dfs.namenode.rpc-address.ns1</name>
      <value>Hadoop01:8040</value>
   </property>
.... Other common configuration ...
</configuration>
**********************************************************************

When start the  balancer,the script using the   fs.default.name of
core-site.xml
by defulat.
according to hdfs-site.xml,the port 8020 does no start.So it goes fo fail
when i start the balancer usig the port 8020 of core-site.xml.

So the  ports of  fs.default.name and dfs.namenode.rpc-address.<nameserviceid>
shoud be consistent.


Thanks

Regards
