> Quota Feature Cached Size != Computed Size When Block Committed But Not

>             Project: Hadoop HDFS
>          Issue Type: Bug
>          Components: hdfs, namenode
>    Affects Versions: 2.6.0
>            Reporter: Erik Krogen
>            Assignee: Erik Krogen

> Currently when a block has been committed but has not yet been completed, the 
> cached size (used for the quota feature) of the directory containing that 
> block differs from the computed size. This results in log messages of the 
> following form:
> bq. ERROR namenode.NameNode 
> (DirectoryWithQuotaFeature.java:checkStoragespace(141)) - BUG: Inconsistent 
> storagespace for directory /TestQuotaUpdate. Cached = 512 != Computed = 8192
> When a block is initially started under construction, the used space is 
> conservatively set to a full block. When the block is committed, the cached 
> size is updated to the final size of the block. However, the calculation of 
> the computed size uses the full block size until the block is completed, so 
> in the period where the block is committed but not completed they disagree. 
> To fix this we need to decide which is correct and fix the other to match. It 
> seems to me that the cached size is correct since once the block is committed 
> its size will not change. 
> This can be reproduced using the following steps:
> - Create a directory with a quota
> - Start writing to a file within this directory
> - Prevent all datanodes to which the file is written from communicating the 
> corresponding BlockReceivedAndDeletedRequestProto to the NN temporarily (i.e. 
> simulate a transient network partition/delay)
> - During this time, call DistributedFileSystem.getContentSummary() on the 
> directory with the quota
