Change subject: IMPALA-5624: ProcessStateInfo::ReadProcFileDescriptorInfo() should not fork a process ...................................................................... IMPALA-5624: ProcessStateInfo::ReadProcFileDescriptorInfo() should not fork a process Running shell commands from impalad can be problematic, because using popen leads to forking which causes a spike in virtual memory. To avoid this, "ls" is replaced with posix api calls. FileDescriptorMap fd_desc_ was only used to get the number of file descriptors, so it was unneccesery work to initialize it. It is removed, and only the number of file descriptors is computed. No automatic test is created for this function, because there is no way to know the "expected value" in advance, and the number of file desciptors can change anytime.
