Hi Steve,

I m in process of learning HADOOP.

I have installed HDFS on SUSE-10.

But I m confused what to do next. I searched over Google but not able to
find much about it .

So can anyone suggest what I need to do if I have to implement HDFS for
different databases?

After I commented line
"sslConf.set("proxy.http.test.listener.addr",conf.get("proxy.http.test.liste
ner.addr"));" in HDFSProxy.java getting below error :

Any  ideas how to fix it ?

Sure, it's the temporary code, you can delete that line.

Thanks Denny,

 

Commenting below line in HDFSProxy.java class and rebuilding it . Will this
help ?

sslConf.set("proxy.http.test.listener.addr",conf.get("proxy.http.test.listen
er.addr"));

 

Thanks

In my local Hadoop version, I saw the temporary code with inexistent
property name.

Hashtable does not accept 'null' as the normal value. 

It's the mistake of unit testing

Hi,

I am using Hadoop 1.0.0 and want to try HDFSProxy . Following:

http://hadoop.apache.org/hdfs/docs/r0.21.0/hdfsproxy.html#Jetty-based+Instal
lation+and+Configuration

 

When I run start-hdfsproxy.sh script I get following error in logs :

************************************************************/

2012-02-15 17:32:02,676 INFO org.apache.hadoop.hdfsproxy.HdfsProxy: HDFS

org.apache.hadoop.hdfsproxy.HdfsProxy.createHdfsProxy(HdfsProxy.java:135)

at org.apache.hadoop.hdfsproxy.HdfsProxy.main(HdfsProxy.java:142)

 

After googling around I got this Jira
"https://issues.apache.org/jira/browse/HADOOP-5432"

Should I apply this patch to fix the issue ?

 

Please suggest
