Hi,

I tried to install HDFS federa= tion with the help of document given by you.

I hav= e small issue.
I used 2 slave in setup, both will act as namenode= and datanode.
Now the issue is when I am looking at home pages of both namenodes onl= y one datanode is appearing.
As per my understanding 2 datanodes = should appear in both namenodes home pages.

Can yo= u please let me if am missing any thing?

Thanks,
Sandeep.

Hello~ I am Rho working in korea

I a= m trying to install HDFS Federation( with 2.1.0 beta version ) and to test<= /div>
After 2.1.0 ( for federation =A0test ) install I have a big trouble wh= en file putting test


I command to hadoop
Can you he= lp me to install HDFS Federation and test?
./bin/hadoop fs -put t= est.txt /NN1/

there is error message
"put: Renames across FileSystems not supported"

But ./bin/hadoop fs -put test.txt hdfs://namnode:8020/NN1/ =A0is ok=

Why this is happen? This is very sad to me ^^
Can you explain why this is happend and give me solution?

Additionally

Namenode1= is access to own Namespace( named NN1 ) and Namenode2 is access to own Nam= espace( named NN2 )
When making directory in namenode1 server=A0
./bin/hadoop fs= -mkdir /NN1/nn1_org =A0is ok but ./bin/hadoop fs -mkdir /NN2/nn1_org =A0 i= s error

Error message is "/NN2/nn1_org': = No such file or directory"

I think this is very right

But= in namenode2 server
./bin/hadoop fs -mkdir /NN1/nn2_org =A0is ok= but ./bin/hadoop fs -mkdir /NN2/nn2_org is error
Error message i= s "mkdir: `/NN2/nn2_org': No such file or directory"

I think when making directory in NN1 is error and makin= g directory in NN2 is ok
=A0=A0
Why this is happen and = can you give solution?=A0
