Subject [jira] [Created] (IMPALA-5735) Avoid fork() in ProcessStateInfo
Date Fri, 28 Jul 2017 00:46:02 GMT
Tim Armstrong created IMPALA-5735:

             Summary: Avoid fork() in ProcessStateInfo
                 Key: IMPALA-5735
             Project: IMPALA
          Issue Type: Bug
    Affects Versions: Impala 2.8.0, Impala 2.5.0, Impala 2.6.0, Impala 2.7.0, Impala 2.9.0,
Impala 2.10.0
            Reporter: Tim Armstrong

ReadProcFileDescriptorInfo() forks some processes, which could lead to unpredictable behaviour
or failures when the VM size of the process gets large.

Instead it could read the file directly.
