[jira] Created: (HADOOP-83) infinite retries accessing a missing block

infinite retries accessing a missing block
------------------------------------------

         Key: HADOOP-83
         URL: http://issues.apache.org/jira/browse/HADOOP-83
     Project: Hadoop
        Type: Bug
  Components: dfs  
    Versions: 0.1    
    Reporter: Yoram Arnon


A file in the DFS got corrupted - the reason for that is unknown, but might be justified.

when accessing the file, I get an infinite stream of error messages from the client - attached below.
The client aparently increments an error counter, but never checks it.

Correct behaviour is for the client to retry a few times, then abort.

[jira] Commented: (HADOOP-83) infinite retries accessing a missing block

Posted by "Konstantin Shvachko (JIRA)" <ji...@apache.org>.
    [ http://issues.apache.org/jira/browse/HADOOP-83?page=comments#action_12371503 ] 

Konstantin Shvachko commented on HADOOP-83:
-------------------------------------------

In order to prevent the client from looping infinitely retrying to locate missing block the following line
-                   /**
                    if (failures >= MAX_BLOCK_ACQUIRE_FAILURES) {
                        throw new IOException("Could not obtain block " + blocks[targetBlock]);
                    }
-                   **/
in DFSClient.blockSeekTo(long) should be uncommented.
It is also desired to reduce the value of the MAX_BLOCK_ACQUIRE_FAILURES constant
which is set to 10 now. In current settings it will take at least 100 seconds to detect missing block.
So additionally to uncommenting the lines above I'd set
-   static int MAX_BLOCK_ACQUIRE_FAILURES = 10;
+   static int MAX_BLOCK_ACQUIRE_FAILURES = 3;
and reduce sleeping time between retries to 3 seconds from current 10
                    LOG.info("Could not obtain block from any node:  " + ie);
                    try {
-                       Thread.sleep(10000);
+                       Thread.sleep(3000);
                    } catch (InterruptedException iex) {
                    }

[jira] Resolved: (HADOOP-83) infinite retries accessing a missing block

Posted by "Doug Cutting (JIRA)" <ji...@apache.org>.
     [ http://issues.apache.org/jira/browse/HADOOP-83?page=all ]
     
Doug Cutting resolved HADOOP-83:
--------------------------------

    Resolution: Fixed

Okay, I've commited this.

Note that this situation can occur while a dfs system is starting up.  If one lanuches the namenode prior to the datanodes then the namenode will know about files but not yet know wherre their blocks are, until the datanodes check in for the first time.  I recently changed the bin/start-all.sh script to start the namenode first, so that datanodes would not all initially report problems connecting to the namenode.  I knew there was a reason that it was done in the other order, but could not remember what the reason was.  Now I remember!  I switched that back and added a comment.

Also, next time, can you please attach a patch file, so that I don't have to manually make your suggested changes?  Thanks!
