It wasn't a daemon thread(started from the main thread), the stack trace can
also imply that:
```
"Thread-7" #38 prio=5 os_prio=0 tid=0x00007f813313c000 nid=0x12cc waiting on
condition [0x00007f80f1581000]
java.lang.Thread.State: TIMED_WAITING (sleeping)
at java.lang.Thread.sleep(Native Method)
at
org.apache.hadoop.hive.metastore.HiveMetaStore$5.run(HiveMetaStore.java:11950)
```
compared to a daemon thread, there is a **daemon** flag in the stack trace:
```
"Metastore threads starter thread" #37 daemon prio=5 os_prio=0
tid=0x00007f813313a800 nid=0x12cb waiting on condition [0x00007f80f2b1d000]
```
