---------------------------------
Summary: 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
