[jira] [Created] (IMPALA-5624) ProcessStateInfo::ReadProcFileDescriptorInfo() should not fork a process

Tim Armstrong created IMPALA-5624:
-------------------------------------

             Summary: ProcessStateInfo::ReadProcFileDescriptorInfo() should not fork a process
                 Key: IMPALA-5624
                 URL: https://issues.apache.org/jira/browse/IMPALA-5624
             Project: IMPALA
          Issue Type: Bug
          Components: Backend
    Affects Versions: Impala 2.10.0
            Reporter: Tim Armstrong


Forking processes from the Impala daemon after startup is problematic because of the spike in virtual memory it causes (see IMPALA-2294). We should avoid doing this in ProcessStateInfo::ReadProcFileDescriptorInfo(), which is invoked from the web server debug pages.
