    Hi @tarunbansal Welcome to the team, and please get familiar with our code style at https://cwiki.apache.org/confluence/display/QUICKSTEP/Quickstep+Coding+Standards.
    Also, I noticed that you made the file mode from `644` to `755`. Please revert this change
    Finally, I would have written the code as following:
    // Add in Line 21.
    #include "relational_operators/RelationalConfig.h"  // For QUICKSTEP_HAVE_UNISTD.
    #include <unistd.h>
    // Start from Line 95.
          // Check file permissions before trying to open it.
          const int access_result = access(file.c_str(), R_OK);
          CHECK_EQ(0, access_result)
              << "File " <<  file << " is not readable due to permission
