-----------------------------------------
Summary: commitBlockSynchronization() does not remove locations,
which were not confirmed
Key: HDFS-7930
URL: https://issues.apache.org/jira/browse/HDFS-7930
Project: Hadoop HDFS
Issue Type: Bug
Components: namenode
Affects Versions: 2.7.0

Priority: Blocker
When {{commitBlockSynchronization()}} has less {{newTargets}} than in the
original block it does not remove unconfirmed locations. This results in that
the the block stores locations of different lengths or genStamp (corrupt).
