Kihwal Lee updated HDFS-9574:
-----------------------------
Attachment: HDFS-9574.v3.br27.patch
The patch for branch-2.7 is not very different from the trunk/branch-2 one.
- Simple context differences.
- Difference due to hdfs client split and file moves.
- {{AccessMode}} moved from {{BlockTokenSecretManager}} to
{{BlockTokenIdentifier}}.
> Reduce client failures during datanode restart
