NameNodeConnector#getLiveDatanodeStorageReport() is > OperationCategory.UNCHECKED in FSNamesystem, so we can access SNN directly. > 2. We can share the same UT(testBalancerRequestSBNWithHA) with > NameNodeConnector#getBlocks(). -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
