> EC: infinite lease recovery caused by the length of RWR equals to zero.
> -----------------------------------------------------------------------

> Key: HDFS-17358
> URL: https://issues.apache.org/jira/browse/HDFS-17358
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: ec
> Reporter: farmmamba
> Assignee: farmmamba
> Priority: Major
> Labels: pull-request-available
>
> Recently, there is a strange case happened on our ec production cluster.
> The phenomenon is as below described: NameNode does infinite recovery lease
> of some ec files(~80K+) and those files could never be closed.
>
> After digging into logs and releated code, we found the root cause is below
> codes in method `BlockRecoveryWorker$RecoveryTaskStriped#recover`:
> {code:java}
> // we met info.getNumBytes==0 here!
> if (info != null &&
> info.getGenerationStamp() >= block.getGenerationStamp() &&
> info.getNumBytes() > 0) {
> final BlockRecord existing = syncBlocks.get(blockId);
> if (existing == null ||
> info.getNumBytes() > existing.rInfo.getNumBytes()) {
> // if we have >1 replicas for the same internal block, we
> // simply choose the one with larger length.
> // TODO: better usage of redundant replicas
> syncBlocks.put(blockId, new BlockRecord(id, proxyDN, info));
> }
> }
> // throw exception here!
> checkLocations(syncBlocks.size());
> {code}
> The related logs are as below:
> {code:java}
> java.io.IOException:
> BP-1157541496-10.104.10.198-1702548776421:blk_-9223372036808032688_2938828

> {code}
> because the length of RWR is zero, the length of the returned object in
> below codes is zero. We can't put it into syncBlocks.
> So throw exception in checkLocations method.
