------------------------------------------
Summary: [SBN Read] getBlockLocations() should throw
ObserverRetryOnActiveException on an attempt to change aTime on ObserverNode
Key: HDFS-15099
URL: https://issues.apache.org/jira/browse/HDFS-15099
Project: Hadoop HDFS
Issue Type: Bug
Components: namenode
Affects Versions: 2.10.0
Reporter: Konstantin Shvachko
The precision of updating an INode's aTime while executing
{{getBlockLocations()}} is 1 hour by default. Updates cannot be handled by
ObserverNode, so the call should be redirected to Active NameNode. In order to
redirect to active the ObserverNode should through
{{ObserverRetryOnActiveException}}.
