Subject [jira] Created: (HDFS-1268) Extract blockInvalidateLimit as a seperated configuration
Date Fri, 25 Jun 2010 09:01:49 GMT
Extract blockInvalidateLimit as a seperated configuration

                 Key: HDFS-1268
                 URL: https://issues.apache.org/jira/browse/HDFS-1268
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: name-node
    Affects Versions: 0.22.0
            Reporter: jinglong.liujl

      If there're many file piled up in recentInvalidateSets, only Math.max(blockInvalidateLimit,

20*(int)(heartbeatInterval/1000)) invalid blocks can be carried in a heartbeat.(By default,
It's 100). In high write stress, it'll cause process of invalidate blocks removing can not
catch up with  speed of writing. 
    We extract blockInvalidateLimit  to a sperate config parameter that user can make the
right configure for your cluster.
