Subject [jira] [Commented] (ACCUMULO-101) Include tserver.memory.maps.max in the example xml file
Date Tue, 01 Nov 2011 21:13:32 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-101?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13141603#comment-13141603
] 

Keith Turner commented on ACCUMULO-101:
---------------------------------------

Might be a good idea to put these settings in a xml comment block with a comment suggesting
that these are common things to modify.  The reason for doing this is that by not having them
in a comment block, the setting values in a way become the defacto default (because everyone
will copy this file) overriding the default in the Java enum.

> The default configuration for Accumulo is designed for a server. Being an Apache project,
we will probably get a fair amount of users who just want to grab the code and spin it up
quickly on a regular machine to try it out. I do not think we should change our default settings,
since in the -env.sh file we have everything fairly well documented and java heap errors will
be fairly explicit. However, the in memory map size setting can be more obscure, as it solely
pops up in the .err file (if not using native map, which is not unreasonable for those coming
straight off the shelf). So I think we should put this property in the site.xml-example file
so that the setting name can be easily found and quickly adjusted without as much of a headache.
