-------------------------------
Resolution: Fixed
> MemoryManager tests are flaky
> -----------------------------

> Key: PARQUET-373
> URL: https://issues.apache.org/jira/browse/PARQUET-373
> Project: Parquet
> Issue Type: Bug
> Components: parquet-mr
> Affects Versions: 1.8.0
> Reporter: Ryan Blue
> Assignee: Ryan Blue
> Fix For: 1.9.0
>
>
> The memory manager tests are flaky, depending on the heap allocation for the
> JVM they run in. This is caused by over-specific tests that assert the memory
> allocation down to the byte and the fact that some assertions implicitly cast
> long values to doubles to use the "within" form of assertEquals.
> The tests should not validate a specific allocation strategy, but should
> instead assert that:
> 1. The allocation for a file is the row group size until room runs out
> 2. When scaling row groups, the total allocation does not exceed the pool size
