Gautam Pulla commented on SPARK-26570:
--
I'm hitting a similar issue - but at a more specific line of code - perhaps the
following information will help.
When enumerating a large number of files (2-3 million files) in S3, we see an
OOM at the line of code below which is concatenating all file-paths into a
single string to log them. With 2-3 million paths (each 150 chars), the string
would be 400 million characters - and represented as a JVM multi-byte-per-char
unicode string, that can be close to 1 Gig of memory just to log the string.
With fewer files - say 400k files - the concatenation/logging is successful -
but it's still an annoyance as the output log contains a huge string with all
the enumerated paths.
{code:java}
class InMemoryFileIndex(
...
private[sql] def bulkListLeafFiles(
paths: Seq[Path],
hadoopConf: Configuration,
filter: PathFilter,
sparkSession: SparkSession): Seq[(Path, Seq[FileStatus])] = {
// Short-circuits parallel listing when serial listing is likely to be faster.
if (paths.size <=
sparkSession.sessionState.conf.parallelPartitionDiscoveryThreshold) {
return paths.map { path =>
(path, listLeafFiles(path, hadoopConf, filter, Some(sparkSession)))
}
}
logInfo(s"Listing leaf files and directories in parallel under:
${paths.mkString(", ")}") <<< Log line printing all files

Hsieh commented on SPARK-26570: - First from the stacktrace, I was thinking it is possible that your SerializableFileStatus is too many. Then it is possible to cause OOM when transforming them back to Status. The PR was created for that. But from your latest posts, from jmap logs, looks like SerializableFileStatus do not hold too much memory. Are you sure SerializableFileStatus is the cause of the OOM? > Out of memory when InMemoryFileIndex bulkListLeafFiles > -- > > Key: SPARK-26570 > URL: https://issues.apache.org/jira/browse/SPARK-26570 > Project: Spark > Issue Type: Bug > Components: SQL >Affects Versions: 2.3.2 >Reporter: deshanxiao >Priority: Major > Attachments: image-2019-10-13-18-41-22-090.png, > image-2019-10-13-18-45-33-770.png, image-2019-10-14-10-00-27-361.png, > image-2019-10-14-10-32-17-949.png, image-2019-10-14-10-47-47-684.png, > image-2019-10-14-10-50-47-567.png, image-2019-10-14-10-51-28-374.png, > screenshot-1.png > > > The *bulkListLeafFiles* will collect all filestatus in memory for every query > which may cause the oom of driver.
