Walter Su commented on HDFS-8033:
---------------------------------
upload ByteBufferStrategy_support_len.patch. It fixes the issue.
{code}
// Read from one blockReader up to cell boundary
int cellRet = readBuffer(blockReaders[idxInStripe],
currentNodes[idxInStripe], strategy, off + result,
realLenInCell);
{code}
What does The patch do: When bytebuffer.capacity() > realLenInCell, It only
reads realLenInCell.
> Erasure coding: stateful (non-positional) read from files in striped layout
