Boglarka Egyed updated SQOOP-3243:
----------------------------------
Description:
Importing BLOB data into encrypted zone causes "Stream closed" error with
* BLOB data size bigger than 16MB -> LobFile will be used
* Java 8 -> has a different implementation of the close() method of
FilterOutputStream class

The root cause of this issue is in LobFile.close method, which is being invoked
from the Map cleanup. In line 1669, from the stacktrace, it's trying to close
countingOut OS. However, at line 1664, out OS is already being closed. However,
out OS is just a wrapper of countingOut OS, so at the end, both are pointing to
same instance of CryptoOutputStream. When the call reaches line 1669,
CryptoOutputStream instance is already closed by line 1664. The problem happens
because java.io.BufferedOutputStream will try to call flush on the underlying
OS it's wrapping (in this case, CryptoOutputStream), reaching line 255 of
CryptoOutputStream.
