You need to add a reserved > keyword all the way up the stack & you have to support this variable > long-term if you're going to expose it explicitly to the user. This has > ended up with using Configuration.get() a lot because it is lightweight and > you can tweak settings while you're trying to understand system behavior > [since there are many config params that may never need to be tuned]. We > need to add the ability to put & read arbitrary KV settings in the HBase > schema. Combined with online schema change, this will allow us to safely > iterate on configuration settings. -- This message is automatically generated by JIRA.
