Xuan Gong commented on YARN-1303:
---------------------------------
Did the test on a single node cluster :
Using the command :
{code}
hadoop-3.0.0-SNAPSHOT/bin/hadoop jar
hadoop-yarn-project-3.0.0-SNAPSHOT/share/hadoop/yarn/hadoop-yarn-applications-distributedshell-3.0.0-SNAPSHOT.jar
org.apache.hadoop.yarn.applications.distributedshell.Client --jar
hadoop-yarn-project-3.0.0-SNAPSHOT/share/hadoop/yarn/hadoop-yarn-applications-distributedshell-3.0.0-SNAPSHOT.jar
--shell_command "ls|ps" --num_containers 2
{code}
And From launch_container.sh of Container :
{code}
exec /bin/bash -c "ls|ps
1>/Users/xuan/dep/hadoop-3.0.0-SNAPSHOT/logs/application_1385002853820_0002/container_1385002853820_0002_01_000003/stdout
2>/Users/xuan/dep/hadoop-3.0.0-SNAPSHOT/logs/application_1385002853820_0002/container_1385002853820_0002_01_000003/stderr
"
{code}

> In shell, we can do "ls; ls" to run 2 commands at once.
> In distributed shell, this is not working. We should improve to allow this to
> occur. There are practical use cases that I know of to run multiple commands
> or to set environment variables before a command.
