> Add EC information to BlockLocation
> -----------------------------------
>
> Key: HDFS-12222
> URL: https://issues.apache.org/jira/browse/HDFS-12222
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 3.0.0-alpha1
> Reporter: Andrew Wang
> Assignee: Huafeng Wang
> Labels: hdfs-ec-3.0-nice-to-have
> Attachments: HDFS-12222.001.patch, HDFS-12222.002.patch,
> HDFS-12222.003.patch, HDFS-12222.004.patch
>
>
> HDFS applications query block location information to compute splits. One
> example of this is FileInputFormat:
> https://github.com/apache/hadoop/blob/d4015f8628dd973c7433639451a9acc3e741d2a2/hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-core/src/main/java/org/apache/hadoop/mapred/FileInputFormat.java#L346
> You see bits of code like this that calculate offsets as follows:
> {noformat}
> long bytesInThisBlock = blkLocations[startIndex].getOffset() +
> blkLocations[startIndex].getLength() - offset;
> {noformat}
> EC confuses this since the block locations include parity block locations as
> well, which are not part of the logical file length. This messes up the
> offset calculation and thus topology/caching information too.
> Applications can figure out what's a parity block by reading the EC policy
> and then parsing the schema, but it'd be a lot better if we exposed this more
> generically in BlockLocation instead.
