CR Hota created HDFS-14024:
------------------------------
Summary: RBF: ProvidedCapacityTotal json exception in
NamenodeHeartbeatService
Key: HDFS-14024
URL: https://issues.apache.org/jira/browse/HDFS-14024
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: CR Hota
Assignee: CR Hota
Routers may be proxying for a downstream name node that is NOT migrated to
understand "ProvidedCapacityTotal". updateJMXParameters method in
NamenodeHeartbeatService should handle this without breaking.
{code:java}
jsonObject.getLong("MissingBlocks"),
jsonObject.getLong("PendingReplicationBlocks"),
jsonObject.getLong("UnderReplicatedBlocks"),
jsonObject.getLong("PendingDeletionBlocks"),
jsonObject.getLong("ProvidedCapacityTotal"));
{code}
One way to do this is create a json wrapper while gives back some default if
json node is not found.
