Description
If exception X is thrown in try block, and exception Y is thrown is finally block, X will be swallowed.
In addition, finally block is used to ensure resources are released properly in general. If we throw exception from there, some resources may be leaked. So it's not recommended to throw exception in the finally block
I caught one today and reported HDFS-11794, creating this jira as a master one to catch other similar cases.
Hope there is some static analyzer to find all.
