Konstantin Shvachko commented on HADOOP-4795:
---------------------------------------------
+1.
If the code in internalReleaseLease() below the new IOExceptions you introduced
would throw an exception the data-structures may become inconsistent. But as I
can see these exceptions are not thrown anywhere below under the conditions. We
should commit this.
Another concern that existing images will contain FileUnderConstruction, which
will unclosable forever, and therefore we should investigate how to convert
them into real files in a separate jira.
