Vinayakumar B commented on HADOOP-11590:
----------------------------------------
Thanks [~aw] for the patch.
Some comments.
1. For '\--hostnames' and '\--hosts', if not provided, then 'slaves' file will
be used. This should be mentioned in doc.
2. Executing the below line 2 times in case of Non-HA. which is not necessary.
{code} SECONDARY_NAMENODES=$("${HADOOP_HDFS_HOME}/bin/hdfs" getconf
-secondarynamenodes 2>/dev/null){code}
3. I doubt whether yarn configurations would be loaded while getting this
configurations. Because {{hdfs getconf}} is a Hdfs tool and loads only Hdfs
configurations using {{HdfsConfiguration.init();}}. have you verified this?
{code}+HARM=$("${HADOOP_HDFS_HOME}/bin/hdfs" getconf -confKey
yarn.resourcemanager.ha.enabled 2>&-){code}
> Update sbin commands and documentation to use new --slaves option
