You should look at what libstdc++ is being loaded at runtime. Try putting the gcc 4.8 runtime libraries first in your LD_LIBRARY_PATH and see what happens. I've been burned by this quite a few times. See item 3 in https://gcc.gnu.org/onlinedocs/libstdc++/manual/abi.html; libraries are supposed to be *forward compatible* with NEWER libstdc{{++}}, but if you use an OLDER libstdc{{++}}, then you could have problems

> Hi,
> I have noticed that arrow-cpp's io-hdfs-test fails during compilation with GCC 4.8, but passes when compiled with GCC 5.4 (as it just skips all tests as it doesn't connect to the HDFS client).
> I went into the test output log and it seemed to want me to set the variable ARROW_HDFS_TEST_USER, so I set the variable to 'root' and ARROW_HDFS_TEST_PORT to '9000' (which is the port that I use to connect to my local hdfs) and the test passes.
> Do I need to configure the environment and the variables in a specific way to get it to work?
> I'm mainly asking as I am trying to use arrow and parquet c++ libraries in an external project and I continue to run into segfaults in the libhdfs jni_helper even though I successfully connect to HDFS on my local Hadoop cluster and even read in a single Parquet file and am hoping that somehow this will help me figure out the issue in my external project as well.
> Thank you in advance for your help.
