Karel Vervaeke updated WHIRR-517:
---------------------------------
Attachment: WHIRR-517-evaluation.patch
Attached a patch with proposed implementation.
It adds 3 functions: a generic 'retry' function, 'retry_apt_get' and
'retry_yum'.
For now, I've only changed the zookeeper-cdh implementation for evaluation. If
no-one forsees major problems i'll start replacing all apt-get and yum calls.
I had to change the <filtering> in the pom because it would mess up expressions
like $((tries-1)). (This also explains why JAVA_HOME wasn't being set properly).
> Add a retry loop around apt-get and yum commands to overcome transient errors

> Often, installation on one or more nodes fails because of transient errors
> (mostly failed connection attempts).
> Therefore we should make use of command's built-in retry options and/or add
> our own retry loops.
