Virajith Jalaparti created HDFS-11681:
-----------------------------------------
Summary: DatanodeStorageInfo#getBlockIterator() should return an
iterator to an unmodifiable set.
Key: HDFS-11681
URL: https://issues.apache.org/jira/browse/HDFS-11681
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Virajith Jalaparti
The iterator from {{DatanodeStorageInfo#getBlockIterator()}} should not be
modifiable. Otherwise, calling {{remove}} on the iterator will remove blocks
from {{DatanodeStorageInfo.blocks}}, a function that has to be performed by
calling {{DatanodeStorageInfo#removeBlock}}.
