> h1. bug description
> {code:bash}
> hawq ssh -h sdw2 -h localhost -e 'ls -1 | wc -l'
> {code}
> When running this command, the expected action is that `ls -1 | wc -l` is executed in each host. The expected output is (the number may be different):
> {code:bash}
> [sdw2] ls -1 | wc -l
> [sdw2] 23
> [localhost] ls -1 | wc -l
> [localhost] 20
> {code}
> While the output got is:
> {code:bash}
> 45
> {code}
> The result looks like `ls -l` was executed in each host and the output of `hawq ssh -h sdw2 -h localhost -e 'ls -1'` was redirect to pipe to `wc -l`.
> h2. Another related issue
> {code:bash}
> hawq ssh -h sdw2 -h localhost -e 'kill -9 $(pgrep lava)'
> {code}
> This command expects to kill process named lava in each host. While `$(pgrep lava)` is executed in localhost, and program gets the process id, for example 55555. And then `kill -9 55555` is executed in each host, which is definitely not match with our expect.
