Hi Eric, Thanks for your response. I did get a chance to download the sources from the trunk and partially was also successful in setting up the chukwa stand-alone cluster.
So, what I am doing now is to compile and setup the 0.5.0 chukwa with instructions on this page : http://wiki.apache.org/hadoop/Chukwa_Quick_Start What I could do was to add an adaptor (in the initial_adaptors) for monitoring a file and could see that something was getting written in my hadoop file system with the text that I was appending. There were multiple updates made by other systemmetrics, hadoop, hadoopmetrics etc. Currently I see the following three issues for me to make some more progress with this demo setup .. 1. I modified the hadoop_home/conf/log4j.properties as per the instructions in the QuickStart page. While starting hadoop I see the following messages (not sure if I have to worry about it now .. ). starting namenode, logging to /home/dev/hadoop-0.20.2//logs/hadoop-root -namenode-xtest12.out log4j:WARN No such property [datePattern] in org.apache.log4j.net.Socke tAppender. log4j:WARN No such property [file] in org.apache.log4j.net.SocketAppend er. 2. Apart from the chukwa clinet jar for hadoop, I have also copied json.jar and json*simple*.jar in HADOOP_HOME/lib folder. I get the following in the namenode logs and other logs : What could be going on here ? Exception in thread "Timer thread for monitoring rpc" java.lang.NoClassDefFoundError: org/json/simple/JSONObject at org.apache.hadoop.chukwa.inputtools.log4j.Log4JMetricsContext.emitRecord(Log4JMetricsContext.java:102) at org.apache.hadoop.metrics.spi.AbstractMetricsContext.emitRecords(AbstractMetricsContext.java:306) at org.apache.hadoop.metrics.spi.AbstractMetricsContext.timerEvent(AbstractMetricsContext.java:292) at org.apache.hadoop.metrics.spi.AbstractMetricsContext.access$000(AbstractMetricsContext.java:52) at org.apache.hadoop.metrics.spi.AbstractMetricsContext$1.run(AbstractMetricsContext.java:251) at java.util.TimerThread.mainLoop(Timer.java:512) at java.util.TimerThread.run(Timer.java:462) Caused by: java.lang.ClassNotFoundException: org.json.simple.JSONObject at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) ... 7 more 3. I have configured my hbase properly and was able to also execute the hbase.spec to list out hbase tables etc. With this, when I started ./chukwa hicc .. everything seemed to initialize properly for hicc with embedded jetty. I could load the front page for http://localhost:4080/hicc. But I don't get anything in column and row selection to plot a graph. How do I debug this ? Do I need MySql still, with the hbase present ? Thanks for your help here .. I hope this exercise would be helpful to everyone trying out to setup a chukwa cluster to play around.
