Xuan Gong commented on YARN-1314:
---------------------------------
I am using "--shell_command echo --shell_args HADOOP YARN MAPREDUCE HDFS" to do
the test
Before applied the patch :
The shell script for launching the container will be something like :
{code}
exec /bin/bash -c "echo HADOOP
1>/Users/xuan/dep/hadoop-3.0.0-SNAPSHOT/logs/application_1382474044210_0001/container_1382474044210_0001_01_000002/stdout
2>/Users/xuan/dep/hadoop-3.0.0-SNAPSHOT/logs/application_1382474044210_0001/container_1382474044210_0001_01_000002/stderr
"
{code}
And the output will only show "HADOOP"
After I applied the patch.
The shell script for launching the container will be something like this:
{code}
exec /bin/bash -c "echo HADOOP YARN MAPREDUCE HDFS
1>/Users/xuan/dep/hadoop-3.0.0-SNAPSHOT/logs/application_1382474749963_0001/container_1382474749963_0001_01_000002/stdout
2>/Users/xuan/dep/hadoop-3.0.0-SNAPSHOT/logs/application_1382474749963_0001/container_1382474749963_0001_01_000002/stderr
"
{code}
Then the output will show "HADOOP YARN MAPREDUCE HDFS" as we expected
