Akira AJISAKA commented on MAPREDUCE-5868:
------------------------------------------
I modified Application.java to get error message from the forked process.
{code}
process = runClient(cmd, env);
+ String error = IOUtils.toString(process.getErrorStream());
+ LOG.info(error);
{code}
The error message is as follows:
{code}
bash:
/Users/aajisaka/git/hadoop-common/hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-jobclient/userlogs/job_001_0002/attempt_001_0002_r_000004_5/stdout:
No such file or directory
{code}
It means the process failed immediately because stdout file was missing.
I'll attach a patch to create an empty stdout file.
