Hello Sean Owen, I saw tickets
[SPARK-19835|https://issues.apache.org/jira/browse/SPARK-19835],
[SPARK-19344|https://issues.apache.org/jira/browse/SPARK-19344]. I don't
understand how its relate to my problem, could you explain?
I think the LeaseExpiredException is just tell us that somebody removed
_temporary folder before result was copied to output folder.

> Spark application save into output folder not all files, for example only
> files from 'part-r-00101.avro' to 'part-r-00127.avro', but must be from
> 'part-r-0000.avro' to 'part-r-00127.avro'. It looks like all files was stored
> into _temporary/... but when time to move results to output folder was come,
> files has disappeared from _temporary. In "executiors" logs I saw that all
> task was committed with FileOutputCommitter. There was not tasks preemptions
> and speculation.
