jihoonson commented on issue #6517: Tasks got stuck when upload log files to hdfs URL: https://github.com/apache/incubator-druid/issues/6517#issuecomment-433130391 Ah sorry, my bad. Timeout is necessary, but retrying might not. > In ForkingTaskRunner call taskLogPusher.pushTaskLog(task.getId(), logFile), then stuck here : I mean, what code in `pushTaskLog`? I guess it's `ByteStreams.copy(in, out)`, but do you know why it happens? In `ByteStreams.copy(in, out)`, there's an infinite loop but it's expected to return if there's any exception. Is `FSDataOutputStream.write()` blocking on errors without throwing exceptions?
