----------------------------------------
Summary: Ozone: Optimize number of allocated block rpc by
aggregating multiple block allocation requests
Key: HDFS-12838
URL: https://issues.apache.org/jira/browse/HDFS-12838
Project: Hadoop HDFS
Issue Type: Sub-task
Components: ozone
Affects Versions: HDFS-7240
Reporter: Mukul Kumar Singh
Assignee: Mukul Kumar Singh
Fix For: HDFS-7240
Currently KeySpaceManager allocates multiple blocks by sending multiple block
allocation requests over the RPC. This can be optimized to aggregate multiple
block allocation request over one rpc.
{code}
while (requestedSize > 0) {
long allocateSize = Math.min(scmBlockSize, requestedSize);
AllocatedBlock allocatedBlock =
scmBlockClient.allocateBlock(allocateSize, type, factor);
KsmKeyLocationInfo subKeyInfo = new KsmKeyLocationInfo.Builder()
.setContainerName(allocatedBlock.getPipeline().getContainerName())
.setBlockID(allocatedBlock.getKey())
.setShouldCreateContainer(allocatedBlock.getCreateContainer())
.setIndex(idx++)
.setLength(allocateSize)
.setOffset(0)
.build();
locations.add(subKeyInfo);
requestedSize -= allocateSize;
}
{code}
