Subject [jira] [Commented] (HADOOP-14508) TestDFSIO throws NPE when set -sequential argument.
Date Tue, 20 Jun 2017 08:10:01 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-14508?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16055320#comment-16055320

wenxin he commented on HADOOP-14508:
------------------------------------

hi [~shv], sorry to disturb you.
Would you mind reviewing this patch?

When I use TestDFSIO to benchmark hdfs, I found using -seq options can let TestDFSIO writing
files to hdfs straightly without mr. But I got a NPE when using -seq.

I found TestDFSIO#sequentialTest was broken when we refactoring TestDFSIO, so I try to fix
this issue.

Now, Hadoop QA passed. 
I also tested several use cases below. 

So, would you mind reviewing this? Thanks for you comments.

{code}
hadoop jar hadoop-mapreduce-client-jobclient-3.0.0-alpha4-SNAPSHOT-tests.jar TestDFSIO -write
-seq -size 1GB
hadoop jar hadoop-mapreduce-client-jobclient-3.0.0-alpha4-SNAPSHOT-tests.jar TestDFSIO -read
-seq -size 1GB
hadoop jar hadoop-mapreduce-client-jobclient-3.0.0-alpha4-SNAPSHOT-tests.jar TestDFSIO -read
-seq -random -size 1GB
hadoop jar hadoop-mapreduce-client-jobclient-3.0.0-alpha4-SNAPSHOT-tests.jar TestDFSIO -read
-seq -skipSize 1024 -size 1GB
hadoop jar hadoop-mapreduce-client-jobclient-3.0.0-alpha4-SNAPSHOT-tests.jar TestDFSIO -append
-seq -size 1GB
hadoop jar hadoop-mapreduce-client-jobclient-3.0.0-alpha4-SNAPSHOT-tests.jar TestDFSIO -truncate
-seq -size 1GB
