-----------------------------
Issue Type: Bug (was: Improvement)
> Initialization log for DataTieringManager is incorrect
> ------------------------------------------------------
>
> Key: HBASE-29859
> URL: https://issues.apache.org/jira/browse/HBASE-29859
> Project: HBase
> Issue Type: Bug
> Components: regionserver
> Affects Versions: 3.0.0-beta-1
> Reporter: Xiao Liu
> Assignee: Xiao Liu
> Priority: Minor
> Labels: pull-request-available
> Fix For: 3.0.0-beta-2

>
> In the {{DataTieringManager.instantiate}} method, if {{DataTieringFeature}}
> is not enabled, we still see the log message {{{}DataTieringManager is
> already instantiated.{}}}, which is quite confusing. The code is as follows:
> {code:java}
> public static synchronized boolean instantiate(Configuration conf,
> Map<String, HRegion> onlineRegions) {
> if (isDataTieringFeatureEnabled(conf) && instance == null) {
> instance = new DataTieringManager(onlineRegions);
> LOG.info("DataTieringManager instantiated successfully.");
> return true;
> } else {
> LOG.warn("DataTieringManager is already instantiated.");
> }
> return false;
> } {code}
>
