Amar Kamat updated MAPREDUCE-1912:
----------------------------------
Attachment: mapreduce-1912-v1.1.patch
Attaching a patch that adds a Driver class to tools package and makes it the
main-class of the tools.jar. Here is the output of running tools jar :
{code}
node amar$ java -jar build/hadoop-mapred-tools-0.22.0-SNAPSHOT.jar
An example program must be given as the first argument.
Valid program names are:
Distch: A tool to perform distributed chmod
Distcp: A tool to copy data from one hdfs installation to another
HadoopArchives: An archive creation utility.
LogAnalyzer: An utility tool for archiving and analyzing hadoop logs.
Rumen: A tool to extract MapReduce logs and analyze it.
{code}
Note that the lib-jars needed to run the tools are already added to the tool
jar's (manifest) classpath.
Added Rumen.java to the rumen tool which provides a single entry point into
rumen. Here is the output after using the _Rumen_ option :
{code}
node amar$ java -jar build/hadoop-mapred-tools-0.22.0-SNAPSHOT.jar Rumen
An example program must be given as the first argument.
Valid program names are:
-fold: A Rumen tool fold/scale the trace
-generate-trace: A Rumen tool to generate traces from MapReduce logs.
{code}
Changed TraceBuilder and Folder to print the usage message when invoked with
invalid arguments. Example
{code}
node amar$ java -jar build/hadoop-mapred-tools-0.22.0-SNAPSHOT.jar Rumen -fold
Invalid paramters!!
Usage :
Folder [generic-options] [-output-duration] [-input-cycle] [-concentration]
[-debug] [-allow-missorting] [-seed] [-skew-buffer-length] [-temp-directory]
<input> <output>
Generic options supported are
-conf <configuration file> specify an application configuration file
-D <property=value> use value for given property
-fs <local|namenode:port> specify a namenode
-jt <local|jobtracker:port> specify a job tracker
-files <comma separated list of files> specify comma separated files to be
copied to the map reduce cluster
-libjars <comma separated list of jars> specify comma separated jar files to
include in the classpath.
-archives <comma separated list of archives> specify comma separated
archives to be unarchived on the compute machines.
The general command line syntax is
bin/hadoop command [genericOptions] [commandOptions]
{code}
tets-patch and ant-test passed on my box.
