Bob Hansen created HDFS-9144: -------------------------------- Summary: Refactor libhdfs into stateful/ephemeral objects Key: HDFS-9144 URL: https://issues.apache.org/jira/browse/HDFS-9144 Project: Hadoop HDFS Issue Type: Sub-task Affects Versions: HDFS-8707 Reporter: Bob Hansen
In discussion for other efforts, we decided that we should separate several concerns: * A posix-like FileSystem/FileHandle object (stream-based, positional reads) * An ephemeral ReadOperation object that holds the state for reads-in-progress, which consumes * An immutable FileInfo object which holds the block map and file size (and other metadata about the file that we assume will not change over the life of the file) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
