[jira] [Created] (HAMA-764) In SpillingQueue, spilling thread dos
not start when messages number less than threshold
MaoYuan Xian created HAMA-764:
---------------------------------
Summary: In SpillingQueue, spilling thread dos not start when messages number less than threshold
Key: HAMA-764
URL: https://issues.apache.org/jira/browse/HAMA-764
Project: Hama
Issue Type: Bug
Components: bsp core
Affects Versions: 0.7.0
Reporter: MaoYuan Xian
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 in not invoked, and handleSpilledBuffer method of SpilledDataProcessor can not get the chance to run.
