> HDFS backing storage is useful for following scenarios.
> 1. For Hadoop clusters which don't run HBase.
> 2. For fallback from HBase when HBase cluster is temporary unavailable. Quoting ATS design
document of YARN-2928:
> {quote}
> In the case the HBase
> storage is not available, the plugin should buffer the writes temporarily (e.g. HDFS),
and flush
> them once the storage comes back online. Reading and writing to hdfs as the the backup
storage
> could potentially use the HDFS writer plugin unless the complexity of generalizing the
HDFS
> writer plugin for this purpose exceeds the benefits of reusing it here.
