Tsz Wo Nicholas Sze commented on HDFS-8287:
-------------------------------------------
{code}
if (bufReady == null) {
try {
wait();
} catch(InterruptedException ie) {
throw DFSUtil.toInterruptedIOException("flip interrupted.", ie);
}
}
{code}
It is better to replace "if (bufReady == null)" above with "while (bufReady ==
null)" although using "if" is correct in this case.
> DFSStripedOutputStream.writeChunk should not wait for writing parity

> When a stripping cell is full, writeChunk computes and generates parity
> packets. It sequentially calls waitAndQueuePacket so that user client cannot
> continue to write data until it finishes.
> We should allow user client to continue writing instead but not blocking it
> when writing parity.
