Yongjun Zhang created HDFS-6030:
-----------------------------------
Summary: to remove a redundant/unused constructor in INode.java
Key: HDFS-6030
URL: https://issues.apache.org/jira/browse/HDFS-6030
Project: Hadoop HDFS
Issue Type: Task
Reporter: Yongjun Zhang
Priority: Trivial
When I look at fix of HDFS-4879, I noticed that class BlocksMapUpdateInfo in
INode.java, has a constructor that still uses ArrayList<Block> (which
HDFS-4879 tries to replace with ChunkedArrayList for better memory efficiency)
{code}
public static class BlocksMapUpdateInfo {
......
public BlocksMapUpdateInfo(List<Block> toDeleteList) {
this.toDeleteList = toDeleteList == null ? new ArrayList<Block>()
: toDeleteList;
}
......
}
{code}
It turns out that this constructor is not used anywhere. I'm filing this JIRA
to remove it.
