Jim Brennan commented on HDFS-15813:
------------------------------------
Thanks for the review [~kihwal]!
Jira for {{TestUnderReplicatedBlocks#testSetRepIncWithUnderReplicatedBlocks}} :
[HDFS-9243]
Jira for {{TestNameNodeMXBean.testDecommissioningNodes}}: [HDFS-15411]
I filed Jira [HDFS-15823] for {{TestReconstructStripedFileWithRandomECPolicy}}.
It looks like an attempt was made to fix this bug in [HDFS-15308], but it is
still happening in some cases.
> DataStreamer: keep sending heartbeat packets while streaming
> ------------------------------------------------------------
>
> Key: HDFS-15813
> URL: https://issues.apache.org/jira/browse/HDFS-15813
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: hdfs
> Affects Versions: 3.4.0
> Reporter: Jim Brennan
> Assignee: Jim Brennan
> Priority: Major
> Attachments: HDFS-15813.001.patch, HDFS-15813.002.patch,
> HDFS-15813.003.patch, HDFS-15813.004.patch

>
> In response to [HDFS-5032], [~daryn] made a change to our internal code to
> ensure that heartbeats continue during data steaming, even in the face of a
> slow disk.
> As [~kihwal] noted, absence of heartbeat during flush will be fixed in a
> separate jira. It doesn't look like this change was ever pushed back to
> apache, so I am providing it here.
