[Starcluster] connection.execute behavior
This archive was generated by
Here are two places where behavior of executing a command via
connection.execute is different from executing it at the actual shell,
1) I can run this command fine at the actual shell of one of my node, when
logged in as root:
su gotdata -c "ssh -f -N -L 27017:localhost:27017
It runs, returns without blocking, doing exactly what I want (establishing
an ssh tunnel from one node to another on port 27017).
But when I try to execute this command over the execute method in the
starcluster shell, it DOES block:
solr_conn.execute('su gotdata -c "ssh -f -N -L 27017:localhost:27017
... and only returns when I manually kill the ssh tunnel that it starts.
What should I do to get what I want?
2) The same command, minus the su part, runs fine at the actual shell:
ssh -f -N -L 27017:localhost:27017
but when I run this command via the execute method, it fails:
In : solr_conn.execute('ssh -f -N -L 27017:localhost:27017
Out: ['Host key verification failed.']
Why is the behavior different?
