-------------------------------------
Summary: Do not use zero as the beginning number for commands for
LinuxContainerExecutor
Key: YARN-3211
URL: https://issues.apache.org/jira/browse/YARN-3211
Project: Hadoop YARN
Issue Type: Bug
Reporter: Liang-Chi Hsieh
Priority: Minor
Current the implementation of LinuxContainerExecutor and container-executor
uses some numbers as its commands. The commands begin from zero
(INITIALIZE_CONTAINER).
When LinuxContainerExecutor gives the numeric command as the command line
parameter to run container-executor. container-executor calls atoi() to parse
the command string to integer.
However, we know that atoi() will return zero when it can not parse the string
to integer. So if you give an non-numeric command, container-executor still
accepts it and runs INITIALIZE_CONTAINER command.
I think it is wrong and we should not use zero as the beginning number of the
commands.
