> 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
