[jira] [Updated] (HIVE-15570) LLAP: Exception in HostAffinitySplitLocationProvider when running in container mode

["Zhiyuan Yang (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HIVE-15570?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Zhiyuan Yang updated HIVE-15570:
--------------------------------
    Attachment: HIVE-15570.3.patch

Thanks [~sseth] and [~sershe]! I've revised the patch according to your comments. Now it simply ignores 'hive.llap.client.consistent.splits' in container mode. If it's in llap mode but no daemon is available, an error will be thrown.

> Sometimes user might prefer to run with "hive.execution.mode=container" mode when LLAP is stopped. If hive config for LLAP had "hive.llap.client.consistent.splits=true" in client side, it would end up throwing the following exception in {{Utils.java}}.
