[jira] Commented: (HBASE-2328) Make important configurations more obvious to new users

["Jean-Daniel Cryans (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-2328?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12845565#action_12845565 ] 

Jean-Daniel Cryans commented on HBASE-2328:
-------------------------------------------

Ah I can also think of example client configurations. Currently it's really hard to decipher the text telling you to either put the quorum address or use the same hbase-site.xml from the cluster.

> Over the last 2 weeks, I encountered many situations where people didn't set file descriptors and xcievers higher and that was causing a ton of problems that are hard to debug if you're not used to them. To improve that we should:
>  - Refuse to start HBase if ulimit -n returns some small number smaller than 2048, or at least print out in big red blinking letters that the current configuration is bad and then link to a simple troubleshooting entry on the wiki.
>  - Write a clearer Getting Started document where we don't give as much explanations but add more stuff like "this is what your hbase-site.xml/hdfs-site/xml should look like now" and give a complete file example. At this point we don't even give a number for xcievers and we expect new users to come up with one.
> Any other low hanging fruit others can think of?
