    Hi,

    I am unable to find the jars hadoop-test-* in the HDP2.0.* versions and hence not able to do the performance checks (like commands TESTDFSIO). Please let me know where these jars wil be available or how can theses kinds of tests be done in HDP 2.0

    Thanks,
    Arun

    Use the locate command with xargs if you have both:

    [ads@zlabads23 hadoop-mapreduce]$ locate hadoop-mapreduce*.jar | xargs grep DFS
    Binary file /usr/lib/hadoop-mapreduce/hadoop-mapreduce-client-jobclient-2.4.0.2.1.2.0-402-tests.jar matches

    Thanks.

    I was able to find the JARS, but still unable to execute the commands. I tried doing the testing in both HDP 2.0.2 and HDP 2.0.6 but getting the ‘No such method error’. Below is the error , please let me know if there is a solution.

    # hadoop jar /usr/lib/hadoop-0.20-mapreduce/hadoop-test.jar TestDFSIO -write -nrFiles 10 -fileSize 100

    It is present under the directory /usr/lib/hadoop-mapreduce and the jar is : hadoop-mapreduce-examples-2.2.0.2.0.6.0-76.jar. Hope it helped.
