Work Description: steveloughran commented on pull request #2294:
URL: https://github.com/apache/hadoop/pull/2294#issuecomment-690183135
Looking at this a bit more
* its the use of buffer which causes the OOM not the thread pooling, so
neither this nor its predecessor patch will directly fix that
* need to support a bytebuffer pool with max capacity and/or disk buffering

> Project: Hadoop Common
> Issue Type: Bug
> Components: fs/azure
> Affects Versions: 3.3.0

> OutOfMemory error due to new ThreadPools being made each time
> AbfsOutputStream is created. Since threadPool aren't limited a lot of data is
> loaded in buffer and thus it causes OutOfMemory error.
> Possible fixes:
> - Limit the number of ThreadCounts while performing hdfs copyFromLocal (Using
> -t property).
> - Reducing OUTPUT_BUFFER_SIZE significantly which would limit the amount of
> buffer to be loaded in threads.
> - Don't create new ThreadPools each time AbfsOutputStream is created and
> limit the number of ThreadPools each AbfsOutputStream could create.
