Attachment: HDFS-11094.009-b2.patch
[~liuml07], attaching a branch-2/branch-2.8 patch. Just had to change around
the type definitions of some things. Also moved {{NNHAStatusHeartbeatProto}}
from DatanodeProtocol.proto to HdfsServer.proto (which is imported by
DatanodeProtocol.proto) so that it could be used by {{NamespaceInfoProto}}.

I mocked out most of it, so the tests should be pretty simple. But a review to make sure that I'm testing what I think I'm testing would be appreciated. > Send back HAState along with NamespaceInfo during a versionRequest as an > optional parameter > --- > > Key: HDFS-11094 > URL: https://issues.apache.org/jira/browse/HDFS-11094 > Project: Hadoop HDFS > Issue Type: Bug > Components: datanode >Reporter: Eric Badger >Assignee: Eric Badger > Attachments: HDFS-11094.001.patch, HDFS-11094.002.patch, > HDFS-11094.003.patch, HDFS-11094.004.patch, HDFS-11094.005.patch, > HDFS-11094.006.patch, HDFS-11094.007.patch, HDFS-11094.008.patch > > > The datanode should know which NN is active when it is connecting/registering > to the NN.

Description: The datanode should know which NN is active when it is
connecting/registering to the NN. Currently, it only figures this out during
its first (and subsequent) heartbeat(s) and so there is a period of time where
the datanode is alive and registered, but can't actually do anything because it
doesn't know which NN is active. A byproduct of this is that the MiniDFSCluster
will become active before it knows what NN is active, which can lead to NPEs
when calling getActiveNN(). (was: {noformat}
java.lang.NullPointerException: null
at
org.apache.hadoop.hdfs.server.datanode.TestLargeBlockReport.testBlockReportSucceedsWithLargerLengthLimit(TestLargeBlockReport.java:96)
{noformat})
Summary: Send back HAState along with NamespaceInfo during a
versionRequest as an optional parameter (was: TestLargeBlockReport fails
intermittently)
