       Sorry @dengzhhu653, I was distracted by other tasks.

Review comment:
       In our production(standalone or embeded metastore),  the `init` is always set to false:
   standalone: main -> https://github.com/apache/hive/blob/4909ba369cc331a1b490e23b73cbb2cb43f29bd9/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/HiveMetaStore.java#L314 -> https://github.com/apache/hive/blob/4909ba369cc331a1b490e23b73cbb2cb43f29bd9/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/HiveMetaStore.java#L370
   
   embeded: https://github.com/apache/hive/blob/4909ba369cc331a1b490e23b73cbb2cb43f29bd9/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/HiveMetaStore.java#L118-L134
   
   then we init the handler in RetryingHMSHandler,
   https://github.com/apache/hive/blob/4909ba369cc331a1b490e23b73cbb2cb43f29bd9/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/RetryingHMSHandler.java#L80

   LGTM. Compaction does log/store the thread ids, but it gets those directly from Thread#getId.

Review comment:
       The `init` is true only in our tests,  so I propose to remove the parameter `init` here, so that we follow the same style, i.e, the handler can not be used until after the method `init` has been called.
