Allow a block to complete if the number of replicas on live nodes, decommissioning nodes and nodes in maintenance mode satisfies minimum replication factor. The fix prevents block recovery failure if replica of last block is being decommissioned. Vice versa, the decommissioning will be stuck, waiting for the last block to be completed. In addition, file close() operation will not fail due to last block being decommissioned.
Switch the default ADLS access token provider type from Custom to ClientCredential.
New fsck option “-upgradedomains” has been added to display upgrade domains of any block.
