ZanderXu updated HDFS-16623:
----------------------------
Description:
In our production environment, an IllegalArgumentException occurred in the
LifelineSender at one DataNode which was undergoing GC at that time.
And the bug code is at line 1060 in BPServiceActor.java, because the sleep time
is negative.
{code:java}
while (shouldRun()) {
try {
if (lifelineNamenode == null) {
lifelineNamenode = dn.connectToLifelineNN(lifelineNnAddr);
}
sendLifelineIfDue();
Thread.sleep(scheduler.getLifelineWaitTime());
} catch (InterruptedException e) {
Thread.currentThread().interrupt();
} catch (IOException e) {
LOG.warn("IOException in LifelineSender for " + BPServiceActor.this,
e);
}
}
{code}
was:In our production environment, an IllegalArgumentException occurred in
