-	<value>true</value>
-	<description>
-	  This enables the retry cache on the namenode. Namenode tracks for
-	  non-idempotent requests the corresponding response. If a client retries the
-	  request, the response from the retry cache is sent. Such operations
-	  are tagged with annotation @AtMostOnce in namenode protocols. It is
-	  recommended that this flag be set to true. Setting it to false, will result
-	  in clients getting failure responses to retried request. This flag must 
-	  be enabled in HA setup for transparent fail-overs.

-	  The entries in the cache have expiration time configurable
-	  using dfs.namenode.retrycache.expirytime.millis.

-	  This parameter configures the heap size allocated for retry cache
-	  (excluding the response cached). This corresponds to approximately
-	  4096 entries for every 64MB of namenode process java heap size.
-	  Assuming retry cache entry expiration time (configured using
-	  dfs.namenode.retrycache.expirytime.millis) of 10 minutes, this

-	  for 10 minutes. As the heap size is increased, the operation rate
