> blockReport doesn't need to invalidate blocks on SBN
> ----------------------------------------------------
>
> Key: HDFS-6424
> URL: https://issues.apache.org/jira/browse/HDFS-6424
> Project: Hadoop HDFS
> Issue Type: Bug

>
> After the fix in https://issues.apache.org/jira/browse/HDFS-6178,
> blockManager no longer compute pending replication work on SBN. As part of
> that, it also stop removing items from invalidateBlocks.
> blocks can still be added to invalidateBlocks on SBN as part of blockReport.
> As a result, the PendingDeletionBlocks metrics will keep going up on SBN.
> To fix that, we don't need to add blocks to invalidateBlocks during
> blockReport for SBN.
