Work Description: tomscut opened a new pull request #3140:
URL: https://github.com/apache/hadoop/pull/3140
JIRA: [HDFS-16088](https://issues.apache.org/jira/browse/HDFS-16088)
As with [HDFS-13183](https://issues.apache.org/jira/browse/HDFS-13183) ,
NameNodeConnector#getLiveDatanodeStorageReport() can also request to SNN to
reduce the ANN load.
There are two points that need to be mentioned:
1. NameNodeConnector#getLiveDatanodeStorageReport() is
OperationCategory.UNCHECKED in FSNamesystem, so we can access SNN directly.
2. We can share the same UT(testBalancerRequestSBNWithHA) with
NameNodeConnector#getBlocks().
