Kihwal Lee commented on HDFS-10343:
-----------------------------------
The array trimming should be a rare event, as failed storage is promptly
removed when reported.
+1 the patch looks good.
> BlockManager#createLocatedBlocks may return blocks on failed storages

> Storage state is ignored when building the machines list. Failed storage
