Subject How to use Rumen?
Date Mon, 13 Sep 2010 20:30:53 GMT
Hi All,

Is there an instruction on how to use rumen?

I tried the following command:

java -cp hadoop-mapred-0.21.0.jar:hadoop-common-0.21.0.jar:hadoop-hdfs-0.21.0.jar:hadoop-mapred-tools-0.21.0.jar:commons-logging-1.1.1.jar:commons-cli-1.2.jar:log4j-1.2.15.jar:jackson-mapper-asl-1.4.2.jar:jackson-core-asl-1.4.2.jar
org.apache.hadoop.tools.rumen.TraceBuilder traceout topologyout
10/09/13 16:26:09 INFO security.Groups: Group mapping impl=org.apache.hadoop.security.ShellBasedUnixGroupsMapping;
10/09/13 16:26:10 WARN rumen.TraceBuilder: No job found in traces:

How do I set the input jobtracker log file?
