Ewan Higgs created HDFS-10769:
---------------------------------
Summary: BlockIdManager.clear doesn't reset the counter for
blockGroupIdGenerator
Key: HDFS-10769
URL: https://issues.apache.org/jira/browse/HDFS-10769
Project: Hadoop HDFS
Issue Type: Bug
Components: hdfs
Affects Versions: 3.0.0-alpha1, 3.0.0-beta1
Reporter: Ewan Higgs
Priority: Minor
BlockIdManager.clear resets the block id generator for contiguous blocks but
not for striped blocks:
{code}
void clear() {
legacyGenerationStamp.setCurrentValue(GenerationStamp.LAST_RESERVED_STAMP);
generationStamp.setCurrentValue(GenerationStamp.LAST_RESERVED_STAMP);
getBlockIdGenerator().setCurrentValue(SequentialBlockIdGenerator
.LAST_RESERVED_BLOCK_ID);
legacyGenerationStampLimit = HdfsConstants.GRANDFATHER_GENERATION_STAMP;
}
{code}
This should have:
{code}
getBlockGroupIdGenerator().setCurrentValue(Long.MIN_VALUE);
{code}
