Mukund Thakur reopened HADOOP-17215:
------------------------------------
Some customer spark jobs are failing intermittently because of this
{noformat}
org.apache.hadoop.fs.PathIOException:
`abfs://[email protected]/warehouse/tablespace/external/hive/audit/bdp/consumption/structured/impala/audit.db/job_status/_SUCCESS':
Input/output error: Parallel access to the create path detected. Failing
request to honor single writer semantics{noformat}
When disabling this, jobs are succeeding. We need to identify why this was
done.

> ABFS: Support for conditional overwrite
> ---------------------------------------
>
> Key: HADOOP-17215
> URL: https://issues.apache.org/jira/browse/HADOOP-17215
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/azure
> Affects Versions: 3.3.0
> Reporter: Sneha Vijayarajan
> Assignee: Sneha Vijayarajan
> Priority: Major
> Labels: abfsactive
> Fix For: 3.3.1, 3.4.0
>
>
> Filesystem Create APIs that do not accept an argument for overwrite flag end
> up defaulting it to true.
> We are observing that request count of creates with overwrite=true is more
> and primarily because of the default setting of the flag is true of the
> called Create API. When a create with overwrite ends up timing out, we have
> observed that it could lead to race conditions between the first create and
> retried one running almost parallel.
> To avoid this scenario for create with overwrite=true request, ABFS driver
> will always attempt to create without overwrite. If the create fails due to
> fileAlreadyPresent, it will resend the request with overwrite=true.
