[jira] Created: (HADOOP-3185) DFSClient should track failures by
block rather than globally
DFSClient should track failures by block rather than globally
-------------------------------------------------------------
Key: HADOOP-3185
URL: https://issues.apache.org/jira/browse/HADOOP-3185
Project: Hadoop Core
Issue Type: Improvement
Reporter: Chris Douglas
Fix For: 0.18.0
Rather than tracking the total number of times DFSInputStream failed to locate a datanode for a particular block, such failures and the the list of datanodes involved should be scoped to individual blocks. In particular, the "deadnode" list should be a map of blocks to a list of failed nodes, the latter reset and the nodes retried per the existing semantics.
