Subject [jira] Commented: (HADOOP-1044) TestDecommission fails because it attempts to transfer block to a dead datanode
Date Tue, 27 Feb 2007 17:53:06 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-1044?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12476246
] 

dhruba borthakur commented on HADOOP-1044:
------------------------------------------

+1. Code reviewed.

One minor comment: there are 5 datanodes and in the second iteration two of the datanodes
are in decommission state. Thus the  test file should get replicated on the remaining three
datanodes. In this is correct, you might want to make numDatanodes = numIterations + 3.

> There are two iterations in TestDecommission.  After the first iteration, one datanode
will be shut down because it was decommissioned.  In the second iteration, while decommissioning
the node, if it attempts to transfer blocks to the shut down node, the test will fail.
