Jersey filter/Interception binding

looks like mainly 3 ways to define the filter/interceptor
1. global binding
by the @Provider annotation and implement the Client/ContaineRequest/ResponseFilter
this would apply to all request/response

2.named binding
by create new annotation of @NameBinding, which annotate the customFilter and resources together to bind them

3. Dynamic binding
by implement the dynamicFeature, which then would check the resource and register/provide corresponding filters for that resource



cannot set niceness : Permission denied

tried to run hadoop several times, which always throw out an exception

localhost: nice: cannot set niceness: Permission denied

checking jps, the only brought up nameNode and resourceManager.

Tried several approaches on set niceness with no avail. somehow actually calling the daemon to start the datanode directly works. (event the permission denied still exist.)

lwpro2@DESKTOP-G92MK3N:~/hadoop/hadoop-2.9.1$ sbin/ start datanode
starting datanode, logging to /home/lwpro2/hadoop/hadoop-2.9.1/logs/hadoop-lwpro2-datanode-DESKTOP-.out
