is the main fix.
> ssh command hangs (gettin stdout/stderr) for vcloud-director
> ------------------------------------------------------------
>
> Key: BROOKLYN-106
> URL: https://issues.apache.org/jira/browse/BROOKLYN-106
> Project: Brooklyn
> Issue Type: Bug
> Affects Versions: 0.7.0-SNAPSHOT
> Reporter: Aled Sage
> Assignee: Aled Sage
> Attachments: debug.log.tgz, jstack.txt, messages.tgz, ssh-stdout.txt
>
>
> When deploying Tomcat to VMware's vcloud-air, to a CentOS 6.4 VM, when
> installing Java it hangs!
> The Brooklyn web-console shows that it is still waiting for a result from the
> ssh command (which executed `sudo -E -n -S -- yum -y --nogpgcheck install
> java-1.7.0-openjdk-devel`).
> However, when logging into the VM I can see that the `yum` command has
> finished, and the /var/log/messages (attached) shows that the install
> completed.
> This fails repeatedly. It used to pass!
> The stdout is at 32040 bytes. The last few lines of the stdout (as shown in
> the web-console) are:
> {noformat}
> Installing : libtasn1-2.3-6.el6_5.x86_64
> 50/56
> Installing : gnutls-2.8.5-14.el6_5.x86_64
> 51/56
> Installing : 1:cups-libs-1.4.2-67.el6.x86_64
> 52/56
> {noformat}
> Could there be some buffer set to 32K, so it's stuck not reading the rest of
> the stdout (but `SshjToolPerformanceTest.testConsecutiveBigStdoutCommands`
> passes)?
> Why else would our ssh command be stuck, not returning?
