slim bouguerra reassigned HIVE-18959: ------------------------------------- > 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 > Priority: Major > 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)
