Andrew Purtell commented on HBASE-1173:
---------------------------------------
Yes I think this can make it. How about something along the lines of:
* Use ssh to retrieve hadoop-site.xml and parse for root FS URI, or ask
** Use 'hadoop fs' to check validity
* Ask about ZK particulars
** Self manage or use existing installation
*** Existing installation details
* Ask for master DNS name
** Check resolution sanity
** Check reachability
** Test auto-ssh
** Use 'cat /proc/cpu' to check for minimum CPU for master and warn if not
** Ask about heap size and enforce minimum requirement
** Use 'free' to check for minimum RAM for master and warn if not
* Ask for HRS DNS names
** Check resolution sanity
** Check reachability
** Test auto-ssh
** Use 'cat /proc/cpu' to check for minimum CPU and warn if not
** Ask about heap size and enforce minimum requirement
** Use 'free' to check for minimum RAM and warn if not
* Ask to make xceivers change to hadoop-site.xml. Ballpark it according to
'free' output.
* Write 'zoo.cfg', 'hbase-env.sh', 'hbase-site.xml', 'regionservers' and use
scp to push them out.
* Parse and update 'hadoop-site.xml' and use scp to push out the modified
version.
* Use ssh to symlink 'hadoop-site.xml' into hbase/conf/
For each question, provide some explanatory text. Provide a reasonable "don't
care" or "don't know" default.
Some small changes to bin/hbase are necessary to support separate -Xmx options
for various daemon types.
Should we do more?
> HBase configuration wizard

> Key: HBASE-1173
> URL: https://issues.apache.org/jira/browse/HBASE-1173
> Project: Hadoop HBase
> Issue Type: Improvement
> Reporter: Andrew Purtell
> Fix For: 0.20.0
>
>
> There are some aspects of HBase configuration that will be daunting for new
> users. For example, Zookeeper configuration needs to list all hosts so it can
> determine quorum. New users won't necessarily even understand the distinction
> between HBase and Zookeeper. Let's produce a bash configuration wizard that
> can generate all necessary config files or file edits based on the answers
> provided to a few simple questions. This will allow neophytes to quickly spin
> up clusters correctly without duplicating common errors. Advanced
> configuration is out of scope for this issue.
