When I try to build the hdfs project following the given scripts, but I don't get the right results. In ~/app/ctest-hadoop/hadoop-hdfs-project/hadoop-hdfs/target/classes directory, there is no core-ctest.xml which I have built in hadoop-common.
I have tried to find the reason, but nothing has been gained.I deteled the .m2 directory, but it doesn't work.
So, do you have any suggestions for me? Thank you so much.

@MEILIDEKCL Thanks for the questions.

The potential solutions are:

1. Please check whether the hadoop is in the ctest-injection branch
2. The name of the file for injection for hdfs is hdfs-ctest.xml instead of core-ctest.xml.
3. And you need to build the hdfs module so that the hdfs-ctest.xml in src will be copied to target.

@Alex-Lian Thanks for your response.

1. I am surely in the ctest-injection branch
2. Yes, hdfs project need hdfs-ctest.xml. But I find that in your source code(ctest_const.py), the INJECTION_PATH for HDFS needs two xml (core-ctest.xml and hdfs-ctest.xml)
3. I followed the scripts add_project.sh ctest gived

@MEILIDEKCL I think it is a bug in the ctest_const.py. For hdfs, we only need to inject value to hdfs-ctest.xml file. I need to double check with @marshtompsxd.

@Alex-Lian Thanks for your help.

We found some test cases in HDFS does not load hdfs-xxx.xml so we injected to both to make sure the injection takes effect. In most cases, injecting to hdfs-ctest.xml should be enough for HDFS.

@marshtompsxd Yeah, Thank you. But is there any questions for buliding the project on HDFS? I mean why core-ctest.xml wasn't compiled into target/class directory? Thank you.

@MEILIDEKCL For Hcommon, the filename for injection is core-ctest.xml. While for HDFS, the filename is hdfs-ctest.xml.

And you can find the hdfs-ctest.xml file here. https://github.com/xlab-uiuc/hadoop/tree/ctest-injection/hadoop-hdfs-project/hadoop-hdfs/src/main/resources

Oh, yeah. Thank you.
