According to the suggestions provided by @cloud-fan @aokolnychyi .I modified
the code.
I added the `isTransient ` attribute to some `error_classes` such as
`AMBIGUOUS_LATERAL_COLUMN_ALIAS`, `CANNOT_PARSE_DECIMAL`, `DATATYPE_MISMATCH`,
`DIVIDE_BY_ZERO`, `_LEGACY_ERROR_TEMP_3043(npe)`
```java
"CANNOT_PARSE_DECIMAL" : {
"message" : [
"Cannot parse decimal."
],
"sqlState" : "22018",
"isTransient" : false
},
```
When these errors occur, the retry logic is skipped.
```java
if (!ef.isTransient) {
// if the exception has an error class which means a non-transient
error, not retry
logError(s"$task has a non-transient exception: ${ef.description};
not retrying")
sched.dagScheduler.taskEnded(tasks(index), reason, null,
accumUpdates, metricPeaks, info)
abort(s"$task has a non-transient exception: ${ef.description}",
ef.exception)
return
}
```
