> 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.
