From 9aeb77023f8e9ca95bdccf79ca9cd5434a2c8aa1 Mon Sep 17 00:00:00 2001 From: Skye Wanderman-Milne Date: Wed, 17 Feb 2016 13:45:47 -0800 Subject: [PATCH] IMPALA-2993: don't check for "Failed to allocate buffer for collection" error This test query is supposed to check the error path for when a collection buffer cannot be allocated. However, it's flaky because the collection allocations are not very big (< 2KB), so it's possible for a different operator to trigger OOM. I think the correct solution is to create a test file that contains very large collections, so a large collection allocation will trigger OOM, rather than many small collection allocations. For now though, let's disable the specific collection allocation check to unblock the build, even though we risk losing coverage.
