[SPARK-24515][CORE] No need to warning when output commit coordination
enabled
## What changes were proposed in this pull request?
No need to warning user when output commit coordination enabled
```
// 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)
}
```
