Zhihua Deng created HIVE-27865:
----------------------------------
Summary: HMS in http mode drops down silently with no errors
Key: HIVE-27865
URL: https://issues.apache.org/jira/browse/HIVE-27865
Project: Hive
Issue Type: Bug
Reporter: Zhihua Deng
After the HIVE-27340, threads in the jetty pool are all daemon threads, such
thread pool does not prevent the JVM from exiting when HMS finishes the main
thread:
{noformat}
metastore-0 metastore 1 96e7e920-067b-4134-9abe-c731d12bc8eb [mdc@18060
class="metastore.HiveMetaStore" level="INFO" thread="main"] Started HTTPServer
for HMS metastore-0 metastore 1 96e7e920-067b-4134-9abe-c731d12bc8eb [mdc@18060
class="hook.AtlasHook" level="INFO" thread="shutdown-hook-0"] ==> Shutdown of
Atlas Hook{noformat}
We should provide a way to avoid the silent shutdown as what we do in
HiveServer2 http mode:
