Gopal V created HIVE-16571: ------------------------------ Summary: HiveServer2: Prefer LIFO over round-robin for Tez session reuse Key: HIVE-16571 URL: https://issues.apache.org/jira/browse/HIVE-16571 Project: Hive Issue Type: Improvement Components: HiveServer2, Tez Affects Versions: 3.0.0 Reporter: Gopal V
Currently Tez session reuse is entirely round-robin, which means a single user might have to run upto 32 queries before reusing a warm session on a HiveServer2. This is not the case when session reuse is disabled, with a user warming up their session on the 1st query. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
