Sushanth Sowmyan commented on HIVE-8850: ---------------------------------------- Note also, that the result of this is that the directsql attempt of getDatabase will not have a rollback executed on it if it fails before falling back to jdo, but that is fine, I think, since it's a read-only operation, and thus, does not need rollback. > ObjectStore:: rollbackTransaction() and getHelper class needs to be looked > into further. > ---------------------------------------------------------------------------------------- > > Key: HIVE-8850 > URL: https://issues.apache.org/jira/browse/HIVE-8850 > Project: Hive > Issue Type: Bug > Components: Metastore > Reporter: Hari Sankar Sivarama Subramaniyan > Assignee: Hari Sankar Sivarama Subramaniyan > Attachments: HIVE-8850.1.patch, HIVE-8850.2.patch > > > We can run into issues as described below: > Hive script adds 2800 partitions to a table and during this it can get a > SQLState 08S01 [Communication Link Error] and bonecp kill all the connections > in the pool. The partitions are added and a create table statement executes > (Metering_IngestedData_Compressed). The map job finishes successfully and > while moving the table to the hive warehouse the ObjectStore.java > commitTransaction() raises the error: commitTransaction was called but > openTransactionCalls = 0. This probably indicates that there are unbalanced > calls to openTransaction/commitTransaction -- This message was sent by Atlassian JIRA (v6.3.4#6332)
