Errors come out when starting Balancer
Hi ALL
I start the Balancer on the HDFS Federation,however it comes an error:
java.net.ConnectException: Call From Hadoop01/10.167.14.221 to
Hadoop01:8020 failed on connection exception: java.net.ConnectException:
Connection refused; For more details see:
http://wiki.apache.org/hadoop/ConnectionRefused. Exiting ...
Balancing took 11.163 seconds
* How Can i solve this.*
*
*
By the way,I have done what explained on the
http://wiki.apache.org/hadoop/ConnectionRefused when i build my basic and
original HDFS cluster.So i think the above error maybe because of another
reasons.
thanks
Regards.

Hi,
A few points:
- The property "fs.default.name" has been deprecated in favor of the
newer name "fs.defaultFS".
- When using nameservice IDs, you shouldn't rely on the RPC address.
That is, your fs.defaultFS should instead simply be "hdfs://ns1", and
the config will load the right RPC that is bound to that NS
automatically from the hdfs-site.xml.

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

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
