> DataNode fails to validate integrity for checksum type NULL when DataNode
> recovers
> -----------------------------------------------------------------------------------
>
> Key: HDFS-5761
> URL: https://issues.apache.org/jira/browse/HDFS-5761
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: datanode
> Affects Versions: 3.0.0
> Reporter: Kousuke Saruta
> Assignee: Kousuke Saruta
> Attachments: HDFS-5761.patch
>
>
> When DataNode is down during writing blocks, the blocks are not filinalized
> and the next time DataNode recovers, integrity validation will run.
> But if we use NULL for checksum algorithm (we can set NULL to
> dfs.checksum.type), DataNode will fail to validate integrity and cannot be
> up.
> The cause is in BlockPoolSlice#validateIntegrity.
> In the method, there is following code.
> {code}
> long numChunks = Math.min(
> (blockFileLen + bytesPerChecksum - 1)/bytesPerChecksum,
> (metaFileLen - crcHeaderLen)/checksumSize);
> {code}
> When we choose NULL checksum, checksumSize is 0 so ArithmeticException will
> be thrown and DataNode cannot be up.
