Huaxiang Sun commented on HBASE-25691:
--------------------------------------
I was able to reproduce this issue at my IMacPro. The issue is that
FileInputStream is created with try-with-resources, so its close() is called
right after the try sentence.
[https://github.com/apache/hbase/blob/master/hbase-server/src/main/java/org/apache/hadoop/hbase/io/hfile/bucket/BucketCache.java#L1078]
FileInputStream is a finalize class, so when this object is garbage collected,
its close() is called again.
Its close() deletes the persistence file. In the failed case, finalized thread
calls previous two FileInputStream objects' close() and deletes the persistence
file.
