Is it possible that follower still hold uncommitted data after truncating and reloading?

Is it possible that follower still hold uncommitted data after truncating
and reloading?
ZKDatabase.loadDataBase() loads data from the most recent snapshot, but
FileTxnLog.truncate() doesn't delete the snapshot files corresponding to
the deleted log files.

 Mahadev,

Applying https://issues.apache.org/jira/browse/ZOOKEEPER-874 to 3.3.4
fails QuorumPeerMainTest
.testHighestZxidJoinLate.
Seems that truncate logic causes failure.
