      Description

      The following code in Datanode.java

            try {
              if (blockScanner != null) {
                blockScanner.deleteBlocks(toDelete);
              }
              data.invalidate(toDelete);
            } catch(IOException e) {
              checkDiskError();
              throw e;
            }
      

      causes check disk to happen in case of any errors during invalidate.

      We have seen errors like :

      2013-03-02 00:08:28,849 WARN org.apache.hadoop.hdfs.server.datanode.DataNode: Unexpected error trying to delete block blk_-2973118207682441648_225738165. BlockInfo not found in volumeMap.

      And all such errors trigger check disk, making the clients timeout.
