> Erasure coding: preallocate multiple generation stamps and serialize updates

> Key: HDFS-9079
> URL: https://issues.apache.org/jira/browse/HDFS-9079
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Affects Versions: HDFS-7285
> Reporter: Zhe Zhang
> Assignee: Zhe Zhang
> Attachments: HDFS-9079-HDFS-7285.00.patch
>
>
> A non-striped DataStreamer goes through the following steps in error handling:
> {code}
> 1) Finds error => 2) Asks NN for new GS => 3) Gets new GS from NN => 4)
> Applies new GS to DN (createBlockOutputStream) => 5) Ack from DN => 6)
> Updates block on NN
> {code}
> To simplify the above we can preallocate GS when NN creates a new striped
> block group ({{FSN#createNewBlock}}). For each new striped block group we can
> reserve {{NUM_PARITY_BLOCKS}} GS's. Then steps 1~3 in the above sequence can
> be saved. If more than {{NUM_PARITY_BLOCKS}} errors have happened we
> shouldn't try to further recover anyway.
