> (TaskMemoryManager.java:381) WARN leak 46.2 MB memory from
> org.apache.spark.util.collection.ExternalAppendOnlyMap@22719fb8

> Program: https://gist.github.com/kutt4n/87cfcd4e794b1865b6f880412dd80bbf
> Debug Log: https://gist.github.com/kutt4n/ba3cf8129999dced34ceadc588856edc
> TaskMemoryManager.java:381 says that it's normal to see leaked memory if one
> of the tasks failed. In this case from the debug log - it is not quite
> apparent which task failed and the reason for failure.
> When the TSV file itself is small the issue doesn’t exist. In this particular
> case, the file is a 21MB clickstream data from wikipedia available at
> https://ndownloader.figshare.com/files/5036392
> Not sure if it is a duplicate of 18181 - If so please close this and could
> track it there
