Josh McKenzie created CASSANDRA-17205:
-----------------------------------------
Summary: File leaks will not be be detected and released due to
strong self-references in the tidier
Key: CASSANDRA-17205
URL: https://issues.apache.org/jira/browse/CASSANDRA-17205
Project: Cassandra
Issue Type: Bug
Reporter: Josh McKenzie
LogTransaction.SSTableTidier holds a reference to a {{Tracker}} which holds
references to both a {{ColumnFamilyStore}} and a {{View}}, both of which hold
refs to SSTableReaders. As per the comment at the top of the SSTableTidier:
{quote}// must not retain a reference to the SSTableReader, else leak detection
cannot kick in
{quote}
We shouldn't hold a reference to the Tracker here; long running unit tests
w/-Dcassandra.debugrefcount=true had this pop up.
