Failed to place enough replicas, still in need of 1 to reach 2 (unavailableStorages=[DISK]

[#1]

Hi,

I'm running a distcopy from one cluster to another and getting below error in the destination namenode log file.

2016-10-13 12:48:09,260 WARN 
blockmanagement.BlockPlacementPolicy
(BlockPlacementPolicyDefault.java:chooseTarget(385)) - Failed to place enough
replicas, still in need of 1 to reach 2 (unavailableStorages=[DISK],
storagePolicy=BlockStoragePolicy{HOT:7, storageTypes=[DISK],
creationFallbacks=[], replicationFallbacks=[ARCHIVE]}, newBlock=true) All
required storage types are unavailable: 
unavailableStorages=[DISK], storagePolicy=BlockStoragePolicy{HOT:7,
storageTypes=[DISK], creationFallbacks=[], replicationFallbacks=[ARCHIVE]} 

In the destination cluster, I'm able to write to hdfs. Cluster health is green.

I also see these .distcp.tmp* file in the destination cluster:

hdfs dfs -ls /mstr/f_opt_wifi_ap_mth_chc/
