-----------------------------------
Summary: HOS times out when cluster is full while Hive-on-MR waits
Key: HIVE-20506
URL: https://issues.apache.org/jira/browse/HIVE-20506
Project: Hive
Issue Type: Improvement
Reporter: Brock Noland
My understanding is as follows:
Hive-on-MR when the cluster is full will wait for resources to be available
before submitting a job. This is because the hadoop jar command is the primary
mechanism Hive uses to know if a job is complete.
Hive-on-Spark will timeout after {{SPARK_RPC_CLIENT_CONNECT_TIMEOUT}} because
the RPC client in the AppMaster doesn't connect back to the RPC Server in HS2.
This is a behavior difference it'd be great to close.
