Jing Zhao commented on HDFS-8270:
---------------------------------
Totally agree this retry logic should not be hardcoded inside of the proxy
creation code. The only concern is whether directly removing this retry may
break some existing applications which depend on this retry. If yes we may have
to make this retry configurable and by default we enable it.
> create() always retried with hardcoded timeout when file already exists

> Project: Hadoop HDFS

> Components: hdfs-client
> Affects Versions: 2.6.0
> Reporter: Andrey Stepachev

> 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.
