Re: libhdfs working for test program when run from ant but failing when run individually
Hi,
The following segmentation fault still exists.
I re wrote my application to use ant, but when I integrate it with libhdfs
it fails saying segmentation fault and exiting with 139.
Please do help, as I have already spent a lot of time on re writing my
application to use hadoop and this one fails for no reason.

I have commented out the line

and passing PLATFORM=linux
as the line was not executing if I just type
make test
separately.
and also changed the line
$(HDFS_TEST): hdfs_test.c
$(CC) $(CPPFLAGS) $ -L$(LIBHDFS_BUILD_DIR) -l$(LIB_NAME)
$(LDFLAGS) -o $@
(have added LDFLAGS, because when run it was complaining that ljvm.so was
not found)
Where am I going wrong? Kindly let me know if I have to provide any other
information.

Hi,
My apologies for bugging the forum again and again.
I am able to get the sample program for libhdfs working. I followed
these
steps.
--- compiled using ant
--- modified the test-libhdfs.sh to include CLASSPATH, HADOOP_HOME,
HADOOP_CONF_DIR, HADOOP_LOG_DIR, LIBHDFS_BUILD_DIR (since I ran
test-libhdfs.sh individually and dint invoke it from ant)
--- The program ran succesfully and was able to write, read and all.
Now I copy the same program to a different directory and use the same
Makefile(used by ant) and modified the variables accordingly. Used
make test
compiled successfully
Used the same test-libhdfs.sh to invoke hdfs_test, but now it fails
saying
Segmentation Fault.
I dont know where it is going wrong.
Cant libhdfs be compiled without using ant? I want to test it and
integrate
libhdfs with my program
Please do reply and help me out as this is driving me crazy.
I can only assume there is something wrong with the values you are
passing for the requisite environment variables: OS_{NAME|OS_ARCH},
SHLIB_VERSION, LIBHDFS_VERSION, HADOOP_{HOME|CONF_DIR|LOG_DIR} since
it works when you run 'make test'.
Sorry it isn't of much help... could you share the values you are
using for these?
Arun
Thanks in advance.
