-----------------------------------
Summary: BlockManager.addStorage fails when DN updates storage
Key: HDFS-6830
URL: https://issues.apache.org/jira/browse/HDFS-6830
Project: Hadoop HDFS
Issue Type: Bug
Components: namenode
Affects Versions: 2.5.0
Reporter: Arpit Agarwal
Assignee: Arpit Agarwal
The call to {{removeStorageInfo}} is wrong because the block is still in the
DatanodeStorage's list of blocks and the callee does not expect it to be.
{code}
} else {
// The block is on the DN but belongs to a different storage.
// Update our state.
removeStorage(getStorageInfo(idx));
added = false; // Just updating storage. Return false.
}
{code}
It is a very unlikely code path to hit since storage updates usually occur via
incremental block reports.
