agent.log  I/O exception (java.net.SocketTimeoutException) caught when processing request: Read timed out
Kumar, Suresh 2012-09-17, 21:00
I have the following in my local host :

 

hadoop-1.0.3

chukwa-incubating-0.5.0

hbase-0.92.2

 

Here are some relevant properties from  chukwa-collector-conf.xml

 

<property>

    <name>writer.hdfs.filesystem</name>

    <value>hdfs://localhost:9000</value>

    <description>HDFS to dump to</description>

  </property>

.........

<property>

    <name>chukwaCollector.http.port</name>

    <value>8081</value>

    <description>The HTTP port number the collector will listen
on</description>

  </property>

 

and collectors

 

http://localhost:8081

 

I see the following in agent.log and http://localhost:4080/hicc is
spinning, any help appreciated.
