------------------------------------
Summary: Fix INodeFile#getBlocks to not return null
Key: HDFS-10764
URL: https://issues.apache.org/jira/browse/HDFS-10764
Project: Hadoop HDFS
Issue Type: Bug
Components: namenode
Affects Versions: 3.0
Reporter: Arpit Agarwal
Assignee: Arpit Agarwal
Not all callers of INodeFile#getBlocks check for null. e.g.
{code}
public final QuotaCounts storagespaceConsumedContiguous(
BlockStoragePolicy bsp) {
...
// Collect all distinct blocks
Set<BlockInfo> allBlocks = new HashSet<>(Arrays.asList(getBlocks()));
{code}
We can either fix each caller or alternatively fix getBlocks to never return
null.
