--------------------------------
Summary: Initialization log for DataTieringManager is incorrect
Key: HBASE-29859
URL: https://issues.apache.org/jira/browse/HBASE-29859
Project: HBase
Issue Type: Improvement
Components: regionserver
Affects Versions: 3.0.0-beta-1
Reporter: Xiao Liu
Assignee: Xiao Liu
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:language=java|borderStyle=solid|theme=RDark|linenumbers=true|collapse=false}
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}
