what null pointer exceptions ( java.lang.nullpointerexception ) , causes them? what methods/tools can used determine cause stop exception causing program terminate prematurely? when declare reference variable (i.e. object) creating pointer object. consider following code declare variable of primitive type int : int x; x = 10; in example variable x int , java initialize 0 you. when assign 10 in second line value 10 written memory location pointed x. but, when try declare reference type different happens. take following code: integer num; num = new integer(10); the first line declares variable named num , but, not contain primitive value. instead contains pointer (because type integer reference type). since did not yet point java sets null, meaning "i pointing @ nothing". in second line, new keyword used instantiate (or create) object of type integer , pointer variable num assigned object. can reference object using dereferencing operator .

i work cloudera manager cdh 5.7.1, supports hive 1.1.0. nifi 1.0.0-beta uses hive 1.2.1. when try use selecthiveql processor, following error: required field 'client_protocol' unset! , means there's version mismatch between hive client , server. any suggestions solve problem? i thought building nifi hive-jdbc dependency version 1.1.0 instead of default 1.2.1 , hope there's better solution. since nifi apache project, builds apache jars (such hive , hadoop). there vendor-specific profiles , build properties can use build nifi particular hadoop distribution. for example try following build nifi distro cdh 5.7.1: mvn clean install -dskiptests -pcloudera -dhadoop.version=2.6.0-cdh5.7.1 -dhive.version=1.1.0-cdh5.7.1 -dhbase.version=1.2.0-cdh5.7.1 the hive processors use hadoop libraries provided nifi hadoop libraries nar, , other nars (like hadoop/hdfs processors) use same libraries nar, best approach build whole thing. otherwise can try replace ha...

in view, have multiple views ( uicollectionviewcell s) that, depending on model, can include uiimageview subview (each separate instance). for case, views don't show uiimageview outnumber ones show it. i can choose either call uiimageview.hidden = false when want views show image, or set image inside image view i.e. uiimageview.image = uiimage(named: ...) . i'm wondering, more performant approach, memory , speed concerns? have feeling difference not significant enough, uiimage(named:) 's caching, want find out. if set uiimageview.image = nil , surely if image in memory, released (then reallocated if reused), suggest it if want sure uiimageview.image (1) not visible, (2) not occupy frame in cell , (3) not imply rendering time, set uiimageview.hidden = true i suggest take both actions. performances not problem here, in opinion (considering have few cells image inside)
