------------------------------------------
Summary: Process AllocWriteIdEvent do not update txnId to
tableWriteIds map in Catalog
Key: IMPALA-12851
URL: https://issues.apache.org/jira/browse/IMPALA-12851
Project: IMPALA
Issue Type: Bug
Components: Catalog
Reporter: Venugopal Reddy K
*Description:*
When CREATE_TABLE event is followed by ALLOC_WRITE_ID_EVENT for a table in the
same batch of MetastoreEventsProcessor.processEvents(), process
AllocWriteIdEvent do not update txnId to tableWriteIds map(i.e.,
org.apache.impala.catalog.Catalog#txnToWriteIds_).
*Root Cause:*
It happens, because we get table from catalog in the AllocWriteIdEvent
constructor. And catalog_.getTable() returns null as the CREATE_TABLE is not
processed by the time of AllocWriteIdEvent construction in this case.
Following events get the catalog table in the constructors:
AllocWriteIdEvent
ReloadEvent
CommitCompactionEvent
