> Key: HBASE-15385
> URL: https://issues.apache.org/jira/browse/HBASE-15385
> Project: HBase
> Issue Type: Bug
> Components: hadoop-azure
> Reporter: Liu Shaohui
> Priority: Critical
>
> When using Wsab file system, we found that a failed atomic folder rename
> operation can never recovery for the destination file deleted in Wasb
> filesystem.
> {quota}
> ls: Attempting to complete rename of file
> hbase/azurtst-xiaomi/data/default/YCSBTest/.tabledesc during folder rename
> redo, and file was not found in source or destination.
> {quote}
> The reason is the the file is renamed to the destination file before the
> crash, and the destination file is deleted by another process after crash. So
> the recovery is blocked during finishing the rename operation of this file
> when found the source and destination files all don't exist.
> See: NativeAzureFileSystem.java #finishSingleFileRename
> Another serious problem is that the recovery of atomic rename operation may
> delete new created file which is same name as the source file, because the
> file system don't check if there are rename operation need be redo.
> Suggestions are welcomed~
