The subclass can be specified via "hadoop.security.saslproperties.resolver.class" configuration property. If not specified, the full set of values specified in hadoop.rpc.protection is used while determining the QOP used for the connection. If a class is specified, then the QOP values returned by the class will be used while determining the QOP used for the connection. + +Note that this change, effectively removes SaslRpcServer.SASL\_PROPS which was a public field.

An unrecognized value was silently assumed to mean authentication.

This limits each component of a file system path to a maximum of 255 bytes in UTF-8 encoding. Attempts to create new files that violate this rule will fail with an error. Existing files that violate the rule are not effected. Previously, dfs.namenode.fs-limits.max-component-length was set to 0 (ignored).

We then take the result of which ever read returns first (the outstanding read is cancelled). This 'hedged' read feature will help rein in the outliers, the odd read that takes a long time because it hit a bad patch on the disc, etc. + +This feature is off by default. To enable this feature, set \<code\>dfs.client.hedged.read.threadpool.size\</code\> to a positive number. The threadpool size is how many threads to dedicate to the running of these 'hedged', concurrent reads in your client. + +Then set \<code\>dfs.client.hedged.read.threshold.millis\</code\> to the number of milliseconds to wait before starting up a 'hedged' read.
