> This jira is for two issues I see in the HBaseFileSystem class:
> 1) Load testing on a 7 node cluster using ycsb insert workload shows that
> static initialization of conf properties results in a slightly better
> throughput. Though the initialization uses HBaseConfiguration.create() call
> which is expensive (and I tried to avoid that in its first version), this
> class is used for most of the filesystem class, and had to invoke an
> additional checkAndSetXX call before making the fs call because it is not
> certain whether the retry properties are set or not. Having initialize them
> in static block removes that limitation.
> 2) Correct semantics for CreatePathXXX method. In case the overwrite flag is
> false and file already exists, underlying fs throws an exception. It should
> be re-thrown to the caller.
