由于需要为hadoop集群采购新的服务器,需要对服务器在hadoop环境下的性能进行测试,所以特地整理了一下hadoop集群自带的测试用例:
-
bin/hadoop jar hadoop-*test*.jar
运行上述命令,可以得到hadoop-*test*.jar自带的测试程序- 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
- $ bin/hadoop jar hadoop-*test*.jar TestDFSIO
- TestDFSIO.0.0.4
- Usage: TestDFSIO -read | -write | -clean [-nrFiles N] [-fileSize MB] [-resFile resultFileName] [-bufferSize Bytes]
hadoop jar hadoop-*test*.jar TestDFSIO -write -nrFiles 10 -fileSize 1000
hadoop jar hadoop-*test*.jar TestDFSIO -read -nrFiles 10 -fileSize 1000
hadoop jar hadoop-*test*.jar TestDFSIO -clean
-
- bin/hadoop jar hadoop-*examples*.jar
- An example program must be given as the first argument.
- Valid program names are:
- aggregatewordcount: An Aggregate based map/reduce program that counts the words in the input files.
- aggregatewordhist: An Aggregate based map/reduce program that computes the histogram of the words in the input files.
- dbcount: An example job that count the pageview counts from a database.
- grep: A map/reduce program that counts the matches of a regex in the input.
- join: A job that effects a join over sorted, equally partitioned datasets
- multifilewc: A job that counts words from several files.
- pentomino: A map/reduce tile laying program to find solutions to pentomino problems.
- pi: A map/reduce program that estimates Pi using monte-carlo method.
- randomtextwriter: A map/reduce program that writes 10GB of random textual data per node.
- randomwriter: A map/reduce program that writes 10GB of random data per node.
- secondarysort: An example defining a secondary sort to the reduce.
- sleep: A job that sleeps at each map and reduce task.
- sort: A map/reduce program that sorts the data written by the random writer.
- sudoku: A sudoku solver.
- teragen: Generate data for the terasort
- terasort: Run the terasort
- teravalidate: Checking results of terasort
- wordcount: A map/reduce program that counts the words in the input files.
hadoop jar hadoop-*examples*.jar teragen <number of 100-byte rows> <output dir>
teravalidate执行验证操作时会输出排序错误的key,当输出结果为空时,表示排序正确hadoop jar hadoop-*examples*.jar terasort <input dir> <output dir>
hadoop jar hadoop-*examples*.jar teravalidate <terasort output dir (= input data)> <teravalidate output dir>
- NameNode基准测试nnbench
- $ bin/hadoop jar hadoop-*test*.jar nnbench
- NameNode Benchmark 0.4
- Usage: nnbench <options>
- Options:
- -operation <Available operations are create_write open_read rename delete. This option is mandatory>
- * NOTE: The open_read, rename and delete operations assume that the files they operate on, are already available. The create_write operation must be run before running the other operations.
- -maps <number of maps. default is 1. This is not mandatory>
- -reduces <number of reduces. default is 1. This is not mandatory>
- -startTime <time to start, given in seconds from the epoch. Make sure this is far enough into the future, so all maps (operations) will start at the same time>. default is launch time + 2 mins. This is not mandatory
- -blockSize <Block size in bytes. default is 1. This is not mandatory>
- -bytesToWrite <Bytes to write. default is 0. This is not mandatory>
- -bytesPerChecksum <Bytes per checksum for the files. default is 1. This is not mandatory>
- -numberOfFiles <number of files to create. default is 1. This is not mandatory>
- -replicationFactorPerFile <Replication factor for the files. default is 1. This is not mandatory>
- -baseDir <base DFS path. default is /becnhmarks/NNBench. This is not mandatory>
- -readFileAfterOpen <true or false. if true, it reads the file and reports the average time to read. This is valid with the open_read operation. default is false. This is not mandatory>
- -help: Display the help statement
$ hadoop jar hadoop-*test*.jar nnbench -operation create_write \ -maps 12 -reduces 6 -blockSize 1 -bytesToWrite 0 -numberOfFiles 1000 \ -replicationFactorPerFile 3 -readFileAfterOpen true \ -baseDir /benchmarks/NNBench-`hostname -s`
