Invalid OperationHandle: OperationHandle   This exception occurs when there are multiple HiveServer2 instances and access them using Zookeeper/Knox with failover configured When a query(irrespective of number of rows) took more time and HS2 is not able to respond within the defined timeout, ZK/KNOX will do a failover to the next available HS2 Since the other HS2 is unaware of the Query/Operation Handle, it throws Invalid OperationHandle exception To solve this problem   Check if we can optimize the query to run faster either by adding a filter or splitting the available data into multiple tables and then query them in separate queries etc Check if HS2 is utilized beyond its capacity like using 200 connections at a given point in time for a 24GB heap of HS2/HMS HMS backend database not able to cope up to serve requests from HMS Check yarn queue has enough capacity to serve the query otherwise query will be in waiting state Check if HDFS is healthy and Namenode is able to respond to the requests without delays Sometimes if Ranger needs to check too many files/directories in HDFS before the query gets executed If Load balancer is used, sticky sessions should be enabled so that one-one relationship gets established for opened connections avoiding failover to another HS2 instance The above explanation holds good for any version of Hive ...
