Subject [jira] [Created] (HDFS-5455) NN needs to update storageMap on first heartbeat
Date Mon, 04 Nov 2013 20:38:18 GMT
Arpit Agarwal created HDFS-5455:
-----------------------------------

             Summary: NN needs to update storageMap on first heartbeat
                 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
            Assignee: 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}

To preserve existing behavior we can just start updating storageMap if we see a new storage
ID in a heartbeart.
