Evans Ye commented on BIGTOP-1669:
----------------------------------
Ok, so there's an issue when configuring only *hadoop* in components settings:
{code}
Error: Could not find dependency Package[hadoop-yarn] for
Kerberos::Host_keytab[yarn] at
/bigtop-home/bigtop-deploy/puppet/modules/hadoop/manifests/init.pp:46
{code}
Tested and this fixed the problem. +1. I'll commit this.
> puppet: Hadoop: Separate dependencies on Kerberos keytabs

>
> When trying to set up a node as only a datanode but with Kerberos security
> class hadoop::kerberos pulls in a dependency on package hadoop-yarn which
> makes puppet fail. This patch puts keytab creation into their respective
> component classes.
> Also it corrects an insufficient dependency on "namenode format" by the
> datanode since the datanode needs the namenode to actually run before it can
> work.
