How to run Test class for HDFS?
Hi all,
I want to run a unit test by using hadoop-hdfs-2.9.2-tests.jar in
hadoop-2.9.2/share/hadoop/hdfs.
1.
It didn't work to run the followed command.
(yarn jar hadoop-2.9.2/share/hadoop/hdfs/hadoop-hdfs-2.9.2-tests.jar
TestWriteRead)
The error message said that there is no main class name.
2.
I also tried to manually compile the wordcount class and it failed.
- javac -classpath ${HADOOP_CLASSPATH} -d
'hdfs-test/TestWriteRead-cp/'
'/home/hduser/hdfs-test/TestWriteRead.java'
- jar -cvf TestRW.jar -c TestWriteRead-cp .
but it didn't work.
How Can I run hdfs-tests.jar ??
Best Regards,
Daegyu Han

Try giving the name as org.apache.hadoop.hdfs.TestWriteRead
With package name
