Review comment:
so, you mean move all "disk", "array", and "byte" options as well to
azure? Or just the config and import this to Azure default values? Otherwise,
we would need to copy all these for all stores implementing Data blocks

> Key: HADOOP-17195
> URL: https://issues.apache.org/jira/browse/HADOOP-17195
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs/azure
> Affects Versions: 3.3.0
> Reporter: Mehakmeet Singh
> Assignee: Mehakmeet Singh
> Priority: Major
> Labels: abfsactive, pull-request-available
> Time Spent: 2h 20m

> 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.
