I am using Elasticsearch 0.90.1. I am attempting to limit the field data  
cache size by using the indices.fielddata.cache.size setting. As per the  
documentation  
at [http://www.elasticsearch.org/guide/reference/index-modules/fielddata/](http://www.elasticsearch.org/guide/reference/index-modules/fielddata/) I  
should be able to put:

indices.fielddata.cache.size: 10GB

...to set an absolute value limit. When I do this and start elasticsearch,  
I get:

1. ElasticSearchParseException[Failed to parse [10GB]]  
NumberFormatException[For input string: "10GB"]

I have tried wrapping this value in double quotes, which fails with the  
same error.

Using a percentage of heap works.

Cheers,  
Brad.

You should use  
indices.fielddata.cache.size: 10gb

Documentation should be edited, i think, or ByteSizeValue.java in package  
org.elasticsearch.common.unit adapted.
