David Mollitor commented on HDFS-15351:
---------------------------------------
Thanks for pinging me [~hemanthboyina] a few times. I have been a bit all over
the place so thanks for you persistence and patients.
Probably should be using {{Collection}} classes instead of native arrays, but
that's not for this ticket.
{code:java}
PendingBlockInfo remove = pendingReconstruction.remove(lastBlock);
if (remove != null) {
List<DatanodeStorageInfo> locations = remove.getTargets();
DatanodeStorageInfo.decrementBlocksScheduled(locations.toArray(new
DatanodeStorageInfo[0]));
}
{code}
> Blocks Scheduled Count was wrong on Truncate
