DataNodeCluster should create blocks with the same generation stamp as the
blocks created in CreateEditsLog
-----------------------------------------------------------------------------------------------------------
Key: HADOOP-5554
URL: https://issues.apache.org/jira/browse/HADOOP-5554
Project: Hadoop Core
Issue Type: Bug
Affects Versions: 0.19.1
Reporter: Hairong Kuang
Assignee: Hairong Kuang
Fix For: 0.19.2, 0.20.0, 0.21.0
HADOOP-5384 makes DataNodeCluster to create blocks with generation stamp
Block#GRANDFATHER_GENERATION_STAMP(0) so simuated datanodes do not crash
NameNode any more. But there is still a problem. CreateEditLogs creates blocks
with generation stamp GenerationStamp#FIRST_VALID_STAMP (1000). Because of the
generation stamp mismatch, all injected blocks are marked as invalid when
NameNode processes block reports.
