-----------------------------------
Summary: NNThroughputBenchmark does not filter generic hadoop
args
Key: HDFS-16120
URL: https://issues.apache.org/jira/browse/HDFS-16120
Project: Hadoop HDFS
Issue Type: Bug
Components: benchmarks
Affects Versions: 2.7.5
Reporter: xuefeng zhao
I notice 'Convert NNThroughputBenchmark to a Tool to allow generic
options'(https://issues.apache.org/jira/browse/HDFS-5068) allow generic options
in NNThroughputBenchmark
But when I run NNThroughputBenchmark with generic options ,it not works.
Always print Usage: NNThroughputBenchmark
I check the source code of NNThroughputBenchmark, find that, it does not
support genericOptions now.
main->runBenchmark->ToolRunner.run->run
{code:java}
GenericOptionsParser parser = new GenericOptionsParser(conf, args);
//set the configuration back, so that Tool can configure itself
tool.setConf(conf);
//get the args w/o generic hadoop args
String[] toolArgs = parser.getRemainingArgs();
return tool.run(toolArgs);
{code}
Although `get the args w/o generic hadoop args`, parse still has generic hadoop
args.
