Priyesh K commented on HDDS-15319:
----------------------------------
STORAGE_SPACE_DISTRIBUTION should be finalized to see data in scm for pending
deletion. You can refer following code for the logic.
{code:java}
private DeletedBlocksTransaction constructNewTransaction(
long txID, long containerID, List<DeletedBlock> blocks) {
List<Long> localIdList = blocks.stream().map(b ->
b.getBlockID().getLocalID()).collect(Collectors.toList());
DeletedBlocksTransaction.Builder builder =
DeletedBlocksTransaction.newBuilder()
.setTxID(txID)
.setContainerID(containerID)
.addAllLocalID(localIdList)
.setCount(0);
if
(VersionedDatanodeFeatures.isFinalized(HDDSLayoutFeature.STORAGE_SPACE_DISTRIBUTION))
{
long replicatedSize =
blocks.stream().mapToLong(DeletedBlock::getReplicatedSize).sum();
// even when HDDSLayoutFeature.STORAGE_SPACE_DISTRIBUTION is finalized, old
OM can still call the old API
if (replicatedSize >= 0) {
builder.setTotalBlockReplicatedSize(replicatedSize);
builder.setTotalBlockSize(blocks.stream().mapToLong(DeletedBlock::getSize).sum());
}
long sizePerReplica =
blocks.stream().mapToLong(DeletedBlock::getSizePerReplica).sum();
if (sizePerReplica >= 0) {
builder.setTotalSizePerReplica(sizePerReplica);
}
}
return builder.build();
} {code}
