MaoYuan Xian updated HAMA-764:
------------------------------
Description:
In the SpillingDataOutputBuffer.SpillingStream, we can find the following
implementations to starting the spilling thread.
{code}
private void checkSpillStart() throws IOException {
if (bytesWritten_ >= thresholdSize_) {
try {
startSpilling();
} catch (InterruptedException e) {
throw new IOException("Internal error occured writing to buffer.", e);
}
}
}
{code}
But I encountered the message loss, when total bytes written number is less
than thresholdSize. Because the spilling thread is not invoked, and
handleSpilledBuffer method of SpilledDataProcessor can not get the chance to
run.
