> Make getFileChecksum fail for blocks under construction

> Key: HDFS-8150
> URL: https://issues.apache.org/jira/browse/HDFS-8150
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Kihwal Lee
> Assignee: J.Andreina
> Priority: Critical
> Labels: BB2015-05-RFC
> Attachments: HDFS-8150.1.patch, HDFS-8150.2.patch, HDFS-8150.3.patch

>
> We have seen the cases of validating data copy using checksum then the
> content of target changing. It turns out the target wasn't closed
> successfully, so it was still under-construction. One hour later, a lease
> recovery kicked in and truncated the block.
> Although this can be prevented in many ways, if there is no valid use case
> for getting file checksum from under-construction blocks, can it be disabled?
> E.g. Datanode can throw an exception if the replica is not in the finalized
> state.
