Subject [jira] Commented: (HDFS-833) TestDiskError.testReplicationError fails with locked storage error
Date Fri, 05 Feb 2010 21:14:28 GMT

    [ https://issues.apache.org/jira/browse/HDFS-833?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12830297#action_12830297
] 

Todd Lipcon commented on HDFS-833:
----------------------------------

TestDatanodeBlockScanner failed with this same error here:

http://hudson.zones.apache.org/hudson/job/Hdfs-Patch-h2.grid.sp2.yahoo.net/112/testReport/org.apache.hadoop.hdfs/TestDatanodeBlockScanner/testDatanodeBlockScanner/

/grid/0/hudson/hudson-slave/workspace/Hdfs-Patch-h2.grid.sp2.yahoo.net/trunk/build/test/data/dfs/name1.
The directory is already locked.

though with no stack trace - the test eventually failed with a FileNotFoundException:

{noformat}
java.io.FileNotFoundException: http://localhost:53291/blockScannerReport?listblocks
	at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1288)

	at org.apache.hadoop.hdfs.TestDatanodeBlockScanner.testDatanodeBlockScanner(TestDatanodeBlockScanner.java:129)
{noformat}

(I assume because the NN got in a bad state due to locked storage)
