I followed the guide to install Arrow project from scratch. I met some issues.
1. First of all, I need to build the cpp part. So I setup the thirdparty dependencies. But when I cmake -DCMAKE_INSTALL_PREFIX=$ARROW_HOME .., it shows an error at get_filename_component with FindGTest.cmake. After some digging, I noticed that I have to use cmake 3 (instead of cmake 2).
2. Now I am able to install pyarrow. The installation went smooth. But when I import the module pyarrow, it says ImportError: No module named array. I haven't found any description on this error.
