[jira] [Commented] (HIVE-24359) Hive Compaction hangs because of
doAs when worker set to HS2
[ https://issues.apache.org/jira/browse/HIVE-24359?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17229536#comment-17229536 ]
Rajkumar Singh commented on HIVE-24359:
---------------------------------------
even without HIVE-24089 this will fail/hung if doAs is enabled as we are creating the proxy user here https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/txn/compactor/Worker.java#L539 if table/sds path owner is different than the hive.

> Key: HIVE-24359
> URL: https://issues.apache.org/jira/browse/HIVE-24359
> Project: Hive
> Issue Type: Bug
> Components: HiveServer2, Transactions
> Reporter: Chiran Ravani
> Priority: Critical
>
> When creating a managed table and inserting data using Impala, with compaction worker set to HiveServer2 - in secured environment (Kerberized Cluster). Worker thread hangs indefinitely expecting user to provide kerberos credentials from STDIN
> The problem appears to be because of no login context being sent from HS2 to HMS as part of QueryCompactor and HS2 JVM has property javax.security.auth.useSubjectCredsOnly is set to false. Which is causing it to prompt for logins via stdin, however setting to true also does not helo as the context does not seem to be passed in any case.
> Below is observed in HS2 Jstack. If you see the the thread is waiting for stdin "com.sun.security.auth.module.Krb5LoginModule.promptForName"

> The problem becomes even worse ending up holding all Compilation threads (assuming that valus is restricted by hive.driver.parallel.compilation.global.limit=3) indefinitely and to add more to it compaction process does not run causing too many files (small) and performance issues.
> The issue appears to be after the change in HIVE-24089.
