Summary: DataStreamer#Responder close fails lead the error recovery
Key: HDFS-10820
URL: https://issues.apache.org/jira/browse/HDFS-10820
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Yiqun Lin
Assignee: Yiqun Lin
When worked for HDFS-6532, I found that the error recovery will happens when
responder close fails. The related codes:
{code}
{code:title=DataStreamer.java|borderStyle=solid}
public void run() {
long lastPacket = Time.monotonicNow();
TraceScope scope = null;
while (!streamerClosed && dfsClient.clientRunning) {
// if the Responder encountered an error, shutdown Responder
if (errorState.hasError() && response != null) {
try {
response.close();
response.join();
response = null;
} catch (InterruptedException e) {
// If interruptedException happens, the response will not be set to
null
// and that will lead the error recovry.
LOG.warn("Caught exception", e);
}
}
// Here need add a finally block to set response as null
...
{code}
