-------------------------------
Summary: Hive CLI hangs while waiting for a container
Key: TEZ-2034
URL: https://issues.apache.org/jira/browse/TEZ-2034
Project: Apache Tez
Issue Type: Bug
Reporter: Rich Haase
The Hive CLI, with Tez set as the execution engine, hangs if a container cannot
be immediately be allocated as the Tez application master. From a user
perspective this behavior is broken.
Users should be able to start a CLI and execute hive metadata commands without
needing a Tez application master. Since users are accustomed to queries with
Hive on MapReduce taking a long time, but access to the CLI being near
instantaneous, the correct behavior should be to wait for a query to be run
before starting the Tez application master.
This behavior is avoided with the Beeline CLI since it connects through
HiveServer2, however many users are accustomed to using the Hive CLI and should
not be penalized for their choice until the Hive CLI is completely deprecated.
