U can check TestDFSIO, TerraGen ,TerraSort,TerraValidate NNBench, MRBench(For MapReduce)
Above are very well known tools. Run bin/hadoop jar hadoop-*test*.jar # change to your Hadoop installation directory; # if you followed my Hadoop tutorials, this is /usr/local/hadoop $ cd /usr/local/hadoop $ bin/hadoop jar hadoop-*test*.jar An example program must be given as the first argument. Valid program names are: DFSCIOTest: Distributed i/o benchmark of libhdfs. DistributedFSCheck: Distributed checkup of the file system consistency. MRReliabilityTest: A program that tests the reliability of the MR framework by injecting faults/failures TestDFSIO: Distributed i/o benchmark. dfsthroughput: measure hdfs throughput filebench: Benchmark SequenceFile(Input|Output)Format (block,record compressed and uncompressed), Text(Input|Output)Format (compressed and uncompressed) loadgen: Generic map/reduce load generator mapredtest: A map/reduce test check. mrbench: A map/reduce benchmark that can create many small jobs nnbench: A benchmark that stresses the namenode. testarrayfile: A test for flat files of binary key/value pairs. testbigmapoutput: A map/reduce program that works on a very big non-splittable file and does identity map/reduce testfilesystem: A test for FileSystem read/write. testipc: A test for ipc. testmapredsort: A map/reduce program that validates the map-reduce framework's sort. testrpc: A test for rpc. testsequencefile: A test for flat files of binary key value pairs. testsequencefileinputformat: A test for sequence file input format. testsetfile: A test for flat files of binary key/value pairs. testtextinputformat: A test for text input format. threadedmapbench: A map/reduce benchmark that compares the performance of maps with multiple spills over maps with 1 spill Thanks and Regards Amith ________________________________________ From: Joe Bounour [jboun...@ddn.com] Sent: Tuesday, April 24, 2012 2:30 PM To: hdfs-dev@hadoop.apache.org; chengyao Subject: RE: test HDFS Hello Have you looked at TestDFSIO benchmark http://answers.oreilly.com/topic/460-how-to-benchmark-a-hadoop-cluster/ -----Original Message----- From: chengyao [mailto:cheng...@inspur.com] Sent: Monday, April 23, 2012 11:22 PM To: hdfs-dev Subject: test HDFS HI.
