Kihwal Lee commented on HDFS-10939:
---
In {{startFileInt()}}, {{unlock()}} is done in {{getEncryptionKeyInfo()}} and
it is reacquired in {{startFileInt()}}. Is this asymmetry necessary? It looks
like {{getEncryptionKeyInfo()}} is supposed to be called with the write lock
anyway. Wouldn't it make more sense to make it reacquire the lock in its
finally block? Sure, it might incur extra lock-unlock if something fails: If
{{generateEncryptedDataEncryptionKey()}} fails, the lock will be reacquired
from {{getEncryptionKeyInfo()}}. Then release immediately in the finally block
of {{startFileInt()}}. Still I think it is better to organize locking this way
at the price of extra locking on rare failure cases. Correctness wise, the
patch seems fine.
