> Affects Versions: 0.94.19
> Reporter: Jean-Daniel Cryans
> Assignee: Jean-Daniel Cryans

> Some users have been complaining about this message:
> {noformat}
> ERROR org.apache.hadoop.hbase.regionserver.metrics.SchemaMetrics:
> Inconsistent configuration. Previous configuration for using table name in
> metrics: true, new configuration: false
> {noformat}
> The interesting thing is that we see it with default configurations, which
> made me think that some code path must have been passing the wrong thing. I
> found that if SchemaConfigured is passed a null Configuration in its
> constructor that it will then pass null to SchemaMetrics#configureGlobally
> which will interpret useTableName as being false:
> {code}
> public static void configureGlobally(Configuration conf) {
> if (conf != null) {
> final boolean useTableNameNew =
> conf.getBoolean(SHOW_TABLE_NAME_CONF_KEY, false);
> setUseTableName(useTableNameNew);
> } else {
> setUseTableName(false);
> }
> }
> {code}
> It should be set to true since that's the new default, meaning we missed it
> in HBASE-5671.
> I found one code path that passes a null configuration, StoreFile.Reader
> extends SchemaConfigured and uses the constructor that only passes a Path, so
> the Configuration is set to null.
> I'm planning on just passing true instead of false, fixing the problem for
> almost everyone (those that disable this feature will get the error message).
> IMO it's not worth more efforts since it's a 0.94-only problem and it's not
> actually doing anything bad.
> I'm closing both HBASE-10990 and HBASE-10946 as duplicates.
