---------------------------------------
Summary: FixedValueVectors shouldn't set it's data buffer to null
when it fails to allocate it
Key: DRILL-2894
URL: https://issues.apache.org/jira/browse/DRILL-2894
Project: Apache Drill
Issue Type: Bug
Components: Execution - Data Types
Reporter: Deneche A. Hakim
Assignee: Deneche A. Hakim
Fix For: 1.0.0
this is related to DRILL-2893
In _FixedValueVectors.java_ the following allocation methods will set the
_data_ field to null if they fail to allocate properly:
- _allocateNewSafe()_
- _allocateNew(int valueCount)_
- _reAlloc()_
This will cause 2 problems:
1. both _allocateNew(int valueCount)_ and _reAlloc()_ will throw a
_NullPointerException_ when it fails to allocate. This is somewhat properly
taken care of by the calling code
2. when the operators are cleaning up, calling _clear()_ on a vector with a
null data buffer will throw a _NullPointerException_ preventing the cleanup
from finishing up properly
