------------------------------------------

so, I do not understand the part where you added split($components, ",") in $components_tmp = extlookup("components",    split($components, ",")). can you please explain?

> The fix in BIGTOP-1553 introduce an issue that is variable {{$components}} will always be an one item array.
> This can be identified by adding a quick evaluation snippet in {{bigtop/bigtop-deploy/puppet/manifests/cluster.pp}}:
> {code}
> fail("print component[0]: ${$components[0]}")
> {code}
> the output:
> {code}
> Error: print component[0]: hadoopyarnmapred-app at /bigtop-home/bigtop-deploy/puppet/manifests/cluster.pp:83 on node bigtop1.vagrant
> {code}
> Consequently, the following "if" statement for component installation will not be true because it can not match the specific string.
