Subject [jira] [Created] (HDFS-6602) PendingDeletionBlocks on SBN keeps increasing
Date Wed, 25 Jun 2014 16:32:24 GMT
Kihwal Lee created HDFS-6602:
--------------------------------

             Summary: PendingDeletionBlocks on SBN keeps increasing
                 Key: HDFS-6602
                 URL: https://issues.apache.org/jira/browse/HDFS-6602
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 2.5.0
            Reporter: Kihwal Lee
            Priority: Critical


PendingDeletionBlocks is from BlockManager.invalidateBlocks.numBlocks(). It
means this data structure is populated, but IBR (incremental block reports) do not cause deleted
blocks to be removed from it. As a result, the heap usage keeps increasing.
