> The file handle cache has been disabled by default due to two HDFS issues:
> HDFS-12528: Add an option to not disable short-circuit reads on failures
> HDFS-14872: CryptoInputStream should implement unbuffer
> These two issues have been fixed and are now incorporated in the CDH components in the toolchain.
> This means that the file handle cache can be reenabled by default.
