Plamen Jeliazkov commented on HDFS-7056:
----------------------------------------
TestDFSUpgradeFromImage.testUpgradeFromCorruptRel22Image failure seems
unrelated to this work.
I was able to reproduce the test failure locally but the test never performs
any truncate calls.
It fails a Preconditions check when BlockIdManager (via FSNamesystem) performs
clear() -- again, seems like something from HDFS-7381.

> Implementation of truncate in HDFS-3107 does not allow truncating files which
> are in a snapshot. It is desirable to be able to truncate and still keep the
> old file state of the file in the snapshot.
