Nan Zhu created SPARK-5181:
------------------------------
Summary: inaccurate log when WAL is disabled
Key: SPARK-5181
URL: https://issues.apache.org/jira/browse/SPARK-5181
Project: Spark
Issue Type: Bug
Components: Streaming
Affects Versions: 1.2.0
Reporter: Nan Zhu
Currently, even the logManager is not created, we still see the log entry
s"Writing to log $record"
because of the following lines
{code:title=ReceivedBlockTracker.scala|borderStyle=solid}
/** Write an update to the tracker to the write ahead log */
private def writeToLog(record: ReceivedBlockTrackerLogEvent) {
logDebug(s"Writing to log $record")
logManagerOption.foreach { logManager =>
logManager.writeToLog(ByteBuffer.wrap(Utils.serialize(record)))
}
}
{code}
