Subject [jira] [Created] (HDFS-14546) Document block placement policies
Date Tue, 04 Jun 2019 22:43:00 GMT
Íñigo Goiri created HDFS-14546:
----------------------------------

             Summary: Document block placement policies
                 Key: HDFS-14546
                 URL: https://issues.apache.org/jira/browse/HDFS-14546
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Íñigo Goiri


Currently, all the documentation refers to the default block placement policy.
However, over time there have been new policies:
* BlockPlacementPolicyRackFaultTolerant (HDFS-7891)
* BlockPlacementPolicyWithNodeGroup (HDFS-3601)
* BlockPlacementPolicyWithUpgradeDomain (HDFS-9006)

We should update the documentation to refer to them explaining their particularities and probably
how to setup each one of them.
