oozie fails sqoop and shh actions

[d6patte]

Using the cloudera CHD3 demo virtual machine in VMWare Fusion, two problems that I can't resolve in oozie:
(1) the example sqoop-freeform workflow works, but when I try to access a remote PostgreSQL db (which works in sqoop)
the workflow fails with the error message
Launcher ERROR, reason: Main class [org.apache.oozie.action.hadoop.SqoopMain], exit code 1 the example ssh workflow (echo "Hello World" on localhost) fails with info AUTH_FAILED

Both look like a configuration problem somewhere along the line. Any pointers to help resolve these would be very, very welcome!
