> 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?
