--------------------------------
Summary: Reduce recommissioning overhead
Key: HDFS-4075
URL: https://issues.apache.org/jira/browse/HDFS-4075
Project: Hadoop HDFS
Issue Type: Bug
Components: name-node
Affects Versions: 2.0.2-alpha, 0.23.4
Reporter: Kihwal Lee
Assignee: Kihwal Lee
Priority: Critical
When datanodes are recommissioned,
{BlockManager#processOverReplicatedBlocksOnReCommission()} is called for each
rejoined node and excess blocks are added to the invalidate list. The problem
is this is done while the namesystem write lock is held.
