Subject [jira] [Commented] (HDFS-3322) Update file context to use HdfsDataInputStream and HdfsDataOutputStream
Date Thu, 26 Apr 2012 20:05:44 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3322?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13262993#comment-13262993
] 

Tsz Wo (Nicholas), SZE commented on HDFS-3322:
----------------------------------------------

> Is it possible to update the method signature to require HdfsDataInputStream args instead
of using instanceof and casts?

Since reportChecksumFailure(..) is already deprecated, let leave it as-is and remove it later.

> Although not touched in this patch, I'm just curious why HdfsDataInputStream repeatedly
casts its stream to DFSInputStream when the ctor takes a DFSInputStream?

It is because "in" is declared in java.io.FilterInputStream as an InputStream.
