If its a commercial product, just say the name in a comment and we'll guess the closest ASF release to it. thanks > memory leak in distcp run method > > > Key: HADOOP-15697 > URL: https://issues.apache.org/jira/browse/HADOOP-15697 > Project: Hadoop Common > Issue Type: Bug > Components: tools/distcp >Reporter: mahesh kumar behera >Priority: Major > Attachments: gc-root.png > > > in distcp run method, execute is called but the job is not closed.

Do you have a heap dump after the OOM? Without a heapdump or a stacktrace it's hard to know what went wrong exactly. One source of OOM that we are aware of is the file lists (distcp has to get a list of every files) and it can grow to several gigabytes for a large directory. This known issue is addressed by HADOOP-12502. But there could be other issues as well so we'll need more data to understand better. > memory leak in distcp run method > > > Key: HADOOP-15697 > URL: https://issues.apache.org/jira/browse/HADOOP-15697 > Project: Hadoop Common > Issue Type: Bug >Reporter: mahesh kumar behera >Priority: Major > > in distcp run method, execute is called but the job is not closed.
