[jira] [Commented] (DRILL-6352) Investigate
IndexOutOfBoundsException in TestBsonRecordReader
[ https://issues.apache.org/jira/browse/DRILL-6352?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16451855#comment-16451855 ]
Timothy Farkas commented on DRILL-6352:
---------------------------------------
This is pretty misleading. The varchar vector can silently fail allocating and not allocate a vector at all. This leading to an IOB down the line
{code}
try {
final int requestedSize = (int)curAllocationSize;
data = allocator.buffer(requestedSize);
allocationSizeInBytes = requestedSize;
offsetVector.allocateNew();
} catch (OutOfMemoryException e) {
clear();
return false;
}
{code}

> Project: Apache Drill
> Issue Type: Bug
> Reporter: Timothy Farkas

> Priority: Major

> TestBsonRecordReader requires 400kb on the allocator in order to run all tests successfully. Reducing the memory below that to 300kb will cause an IOB

One of the two will be used. Which one is undefined.
