> ------------------------------------------------

> Key: HDFS-5455
> URL: https://issues.apache.org/jira/browse/HDFS-5455
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: namenode
> Affects Versions: Heterogeneous Storage (HDFS-2832)
> Reporter: Arpit Agarwal

> Currently the NN updates {{DatanodeDescriptor#storageMap}} while processing
> block reports but not from heartbeats. This results in the
> {{DatanodeStorageInfo#blockContentsStale}} being stale even after the first
> heartbeat is received.
> {code}
> void receivedBlockReport() {
> if (heartbeatedSinceFailover) {
> blockContentsStale = false;
> {code}
> We need to update storageMap if we see a new storage ID in a heartbeart.
