slim bouguerra created HIVE-18959: ------------------------------------- Summary: Avoid creating extra pool of threads within LLAP Key: HIVE-18959 URL: https://issues.apache.org/jira/browse/HIVE-18959 Project: Hive Issue Type: Task Components: Druid integration Environment: Kerberos Cluster Reporter: slim bouguerra Assignee: slim bouguerra Fix For: 3.0.0
The current Druid-Kerberos-Http client is using an external single threaded pool to handle retry auth calls (eg when a cookie expire or other transient auth issues). First, this is not buying us anything since all the Druid Task is executed as one synchronous task. Second, this can cause a major issue if an exception occurs that leads to shutting down the LLAP main thread. Thus to fix this we should avoid using an external thread pool and handle retrying in a synchronous way. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
