>                 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

>          Time Spent: 1.5h
>  Remaining Estimate: 0h
>
> 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.
