> 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?
