Summary: No need to warning user when output commit coordination
enabled
Key: SPARK-24515
URL: https://issues.apache.org/jira/browse/SPARK-24515
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 2.3.1
Reporter: zhoukang
{code:java}
// When speculation is on and output committer class name contains "Direct", we
should warn // users that they may loss data if they are using a direct output
committer. val speculationEnabled = self.conf.getBoolean("spark.speculation",
false) val outputCommitterClass =
hadoopConf.get("mapred.output.committer.class", "") if (speculationEnabled &&
outputCommitterClass.contains("Direct")) { val warningMessage =
s"$outputCommitterClass may be an output committer that writes data directly to
" + "the final location. Because speculation is enabled, this output committer
may " + "cause data loss (see the case in SPARK-10063). If possible, please use
an output " + "committer that does not have this behavior (e.g.
FileOutputCommitter)." logWarning(warningMessage) }
