> create() always retried with hardcoded timeout when file already exists
> -----------------------------------------------------------------------
>
> Key: HDFS-8270
> URL: https://issues.apache.org/jira/browse/HDFS-8270
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs-client
> Affects Versions: 2.6.0
> Reporter: Andrey Stepachev
> Assignee: J.Andreina
> Attachments: HDFS-8270.1.patch, HDFS-8270.2.patch
>
>
> In Hbase we stumbled on unexpected behaviour, which could
> break things.
> HDFS-6478 fixed wrong exception
> translation, but that apparently led to unexpected bahaviour:
> clients trying to create file without override=true will be forced
> to retry hardcoded amount of time (60 seconds).
> That could break or slowdown systems, that use filesystem
> for locks (like hbase fsck did, and we got it broken HBASE-13574).
> We should make this behaviour configurable, do client really need
> to wait lease timeout to be sure that file doesn't exists, or it it should
> be enough to fail fast.
